Third Sunday of Advent December 12 and 15 by Rev. Zachary DeArmond

The preaching and Baptism “of repentance for the forgiveness of sins” (Luke 3:3) prepare us for the coming of the Lord, Jesus Christ. The historic work of John the Baptist was completed with the first advent of our Lord Jesus in the flesh, but the ministry of the forerunner continues in the preaching of Law and Gospel and in Holy Baptism. Through His messengers, the Lord calls people of all nations to “see the salvation of God” (Luke 3:6). Our haughtiness is removed and our mountains of pride are brought low, but the Lord humbles us in order to exalt us in His mercy. As the Lord has begun this good work of repentance in us, so also does He perfect it by His Word and Holy Spirit, and He “will bring it to completion at the day of Jesus Christ” (Phil. 1:6). He purifies us to be His priestly people, precious in His sight and abounding in faith and love, so that we offer our very lives in righteousness to the Lord (Mal. 3:3–4).

The true tradition of the Church is the Gospel, which is the preaching and administration of Christ Jesus. Other traditions, although not commanded by God, may serve and support that sacred tradition of the Gospel. But the Church dare not “[reject] the commandment of God” in order to establish or hold to “the tradition of men” (Mark 7:8–9). Sinful people attempt to draw near to the Lord “with their mouth” and to honor Him “with their lips,” while their hearts are far removed from Him (Is. 29:13). Yet, He is “the Holy One of Israel,” who brings about salvation by His cross. Therefore, “the wisdom of their wise men shall perish,” but “the deaf shall hear” and “the eyes of the blind shall see” (Is. 29:14–19). This mystery of Christ is profound, for He is the husband of the Church, and He is her Savior. Not because of any works that she has done, but solely for the sake of His great love, He “gave himself up for her, that he might sanctify her, having cleansed her by the washing of water with the word” (Eph. 5:25–26).

The crucified and risen Lord Jesus is with His Church through the word of His apostles, who “are witnesses of all that he did.” He was anointed by God “with the Holy Spirit and with power,” and “he went about doing good and healing all who were oppressed by the devil,” and so He was with those whom He sent “to preach to the people” (Acts 10:38–42). The Holy Spirit is bestowed on those who hear that apostolic preaching, who are “baptized in the name of Jesus Christ,” so that “everyone who believes in him receives forgiveness of sins through his name” (Acts 10:43–44, 48). For as He came by the water of His Baptism, even to the blood of His Passion, so the Spirit testifies to the truth with “the water and the blood” in the apostolic ministry of the Gospel (1 John 5:6–7). By these means, Christ Jesus speaks to us, that His joy may be in us and that our “joy may be full.” For this purpose, He appointed the apostles to “go and bear fruit” in order to make known His divine friendship to us (John 15:11, 15–16)

“God is love,” and He has manifested Himself to us by sending “his only Son into the world, so that we might live through him” (1 John 4:9, 16). By the ministry of the Gospel, “he has given us of his Spirit,” so that we also believe and confess “that Jesus Christ has come in the flesh.” In this way, we “abide in him and he in us,” and we “love one another” (1 John 4:2, 7, 13). Such divine love is exemplified in Philip’s preaching of “the good news about Jesus” to the Ethiopian eunuch. And when “they came to some water,” the eunuch was baptized into the very Gospel that Philip had preached (Acts 8:35–38). That Ethiopian was thereby grafted into “the true vine,” Jesus Christ (John 15:1), just as we are. Already we are clean because of the Word that Christ has spoken to us and by the washing of water with His Word. We now abide in Him by faith in His forgiveness. As He abides in us, both body and soul, with His own body and His blood, He “bears much fruit” in us (John 15:3–5).

The people sinned by speaking “against God and against Moses,” and the Lord called them to repentance by sending fiery serpents, which “bit the people, so that many people of Israel died” (Num. 21:4–6). When the people confessed their sin, the Lord provided a means of rescue from death. He instructed Moses to “make a fiery serpent and set it on a pole,” so that “if a serpent bit anyone, he would look at the bronze serpent and live” (Num. 21:8–9). Thus, God sent His Son into the world, in the likeness of our sin and death, and lifted Him up on the pole of the cross, that whoever looks to Him in faith “may have eternal life” (John 3:14–16). By His cross, “the light has come into the world,” not for condemnation, but “that the world might be saved through him” (John 3:17–19). While we “were dead in the trespasses and sins” in which we once lived (Eph. 2:1), God loved us, calling us to repentance and raising us up with Christ to live “with him in the heavenly places” (Eph. 2:4–6).

The Lord alone “is the everlasting God, the Creator of the ends of the earth” (Is. 40:28). He “sits above the circle of the earth” and “stretches out the heavens like a curtain” (Is. 40:22). Yet, His almighty power is demonstrated chiefly by His mercy and compassion. “He gives power to the faint, and to him who has no might he increases strength” (Is. 40:29). The only begotten Son of the Father, the very Word by whom all things were made, becomes flesh and takes all the poverty and weakness of our sin and death upon Himself, bearing it in His body to the cross. As He dies for us there, He also raises us up, a new creation, in His resurrection from the dead. Thus, by the preaching of this Word, He heals “many who were sick with various diseases,” and He casts out “many demons” (Mark 1:34, 39). And His preaching continues through those whom He has sent, who are “entrusted with a stewardship” to “preach the gospel” (1 Cor. 9:16–17). Thus, we are set free by the Word of Christ, and we exercise our freedom in loving service to others.

Though Ahaz would not ask, the Lord gives a sign to the House of David — “the virgin shall conceive and bear a son, and shall call his name Immanuel” (Is. 7:14). With this promise, He signifies that salvation is by His grace alone. It is no work or achievement of man, but the Lord’s own work and His free gift. The promise is fulfilled as the Son of God is conceived and born of the Virgin Mary, and the sign is received in faith by the House of David in the person of Joseph (Matt. 1:20–24). “Incarnate by the Holy Spirit of the Virgin Mary” (Nicene Creed), God is with us (Immanuel) in the flesh of Jesus, Mary’s Son. Joseph believes that Word of God and so demonstrates a marvelous example in his immediate and quiet obedience, taking Mary to be his wife and caring for her in faith and love. He loves her because the love of God is manifest in this, that “the Father has sent his Son to be the Savior of the world,” to be “the propitiation for our sins” (1 John 4:10–14).

“A great multitude … from all tribes and peoples and languages” cry out, “Salvation belongs to our God who sits on the throne” (Rev. 7:9–10). Faith-filled saints from every place and time with unified voices eternally magnify the Lamb of God. As His beloved children, we, too, “shall see him as he is” (1 John 3:2). Joined with the throng of angels and myriad saints, we shall “serve him day and night in his temple” (Rev. 7:15). In our earthly tension vacillating between saint and sinner, faith and doubt, sacred and profane, we earnestly seek Jesus to calm our fears, comfort our spirits and forgive our sins. The Holy Spirit, through faith in Christ, propels us forward to our eternal home, fortifying us in Word and Sacrament. In the midst of our constant struggle as believers, we need to be blessed. And so we are. The poor in spirit, the meek, the hungry, the thirsty, the merciful, the pure and the persecuted are all blessed, and we will most certainly inherit the kingdom of heaven (Matt. 5:1–12).

Plotting against Jesus, the Pharisees attempted “to entangle him in his words” by asking about the payment of taxes to Caesar (Matt. 22:15). The Lord pointed to coins required for the tax, and He answered that we should “render to Caesar the things that are Caesar’s, and to God the things that are God’s” (Matt. 22:21). But if coins bearing the image of Caesar should be rendered to him, then man — who is made in the image of God — must be rendered to the Lord. That tax is paid for us by the Lord Jesus, the image of God in the flesh, by His self-offering on the cross. And from His cross, as the Lord’s anointed, He reigns as the true Caesar over all nations “from the rising of the sun and from the west” (Is. 45:6). The Lord once called and anointed Cyrus “to subdue nations before him and to loose the belts of kings” (Is. 45:1). Now by the preaching of the Gospel, “in power and in the Holy Spirit” (1 Thess. 1:5), foreigners from all over the world are “turned to God from idols to serve the living and true God” (1 Thess. 1:9–10)

By His cross and resurrection, the Lord has swallowed up death forever, and by His Gospel He “will wipe away tears from all faces, and the reproach of his people he will take away from all the earth” (Is. 25:8). Therefore, “let us be glad and rejoice in his salvation” (Is. 25:9). On the mountain of the Lord of hosts— in His Church on earth, as in the kingdom of heaven — He has made “for all peoples a feast of rich food, a feast of well-aged wine” (Is. 25:6). It is the royal “wedding feast” of the Son of God, “and everything is ready” (Matt. 22:1, 4). Thus, His servants are sent into the highways and byways to invite and gather as many as they find, “both good and bad,” to fill the wedding hall with guests (Matt. 22:8–10). In Holy Baptism, He clothes them all in the “wedding garment” of His own perfect righteousness (Matt. 22:11). Therefore, “do not be anxious about anything, but in everything by prayer and supplication with thanksgiving let your requests be made known to God,” and “rejoice in the Lord always” (Phil. 4:4–6).

In settling His accounts with us, our Lord acts not with anger, but with compassion. He does not imprison us as we deserve, but He forgives all our debts and releases us (Matt. 18:23–27). Therefore, our Lord bids each of us to have “mercy on your fellow servant” and “forgive your brother from your heart” (Matt. 18:33, 35). By the Lord’s forgiveness of our sins, we are free to forgive those who sin against us, because He has been handed over to the jailers in our stead and He has paid our entire debt with His lifeblood. Whether we live or die, we “are the Lord’s” (Rom. 14:8). Since we all will “stand before the judgment seat of God,” we are not to despise our brother (Rom. 14:10), but gladly forgive him. By the grace of God, our brother also “will be upheld, for the Lord is able to make him stand” (Rom. 14:4). Though we daily sin against each other, the Lord intends “to bring it about that many people should be kept alive” (Gen. 50:20). Jesus speaks kindly by His Gospel and promises: “I will provide for you and your little ones” (Gen. 50:21).

The Lord who “laid the foundation of the earth” (Job 38:4) is the Author and Giver of life who governs all things by His Word. His wisdom and power are beyond our understanding, except as He reveals Himself in the incarnate Word, Christ Jesus. He has “entered into the springs of the sea” and “walked in the recesses of the deep” (Job 38:16), and He draws near to us in mercy. We have been “a long way from the land, beaten by the waves” and tossed about by hostile winds (Matt. 14:24). In our mortality and sinful unbelief, we do not always recognize the Lord Jesus. But as we cry out in fear, He speaks tenderly to us, “Do not be afraid,” and He reaches out His hand to save us (Matt. 14:27, 31). “Everyone who calls on the name of the Lord will be saved” (Rom. 10:13), and now we call upon Him in faith, because we have heard “through the word of Christ” (Rom. 10:17). “The word is near you, in your mouth and in your heart” (Rom. 10:8).

The Lord our God has chosen us to be “his treasured possession,” not because of any strength in us, but solely “because the LORD loves” us (Deut. 7:6–8). He is faithful, and He “keeps covenant and steadfast love with those who love him and keep his commandments” (Deut. 7:9). He has searched for us and found us in love, and He has bestowed on us “great value” by the great price that He has paid on the cross (Matt. 13:45–46). In His joy, He has redeemed us by His cross and gathered us into His kingdom by the Gospel. Now we are “hidden in a field,” covered by the cross and subject to the persecution of the world (Matt. 13:44), not for destruction, but “to be conformed to the image of his Son” (Rom. 8:29). Since we “are called according to his purpose” (Rom. 8:28), and because Christ Jesus died, rose again and lives to intercede for us “at the right hand of God” (Rom. 8:34), there is nothing in all creation that can separate us from “the love of God in Christ Jesus our Lord” (Rom. 8:39).

As “the rain and the snow come down from heaven” and “water the earth, making it bring forth and sprout” (Is. 55:10), so the Word of God accomplishes the purpose for which He speaks it, granting joy and peace through the forgiveness of sins and producing the fruits of faith and love in those who are called by His name. Christ Jesus, the incarnate Word, has established the name of the Lord as “an everlasting sign that shall not be cut off” (Is. 55:13). He opens our ears to hear, our minds to understand and our hearts to believe His Word, lest the evil one come and snatch it away. He thus transforms our rocky hearts into good soil, which clings to the Gospel and “indeed bears fruit” (Matt. 13:23). He is Himself the firstfruits of all who “have received the Spirit of adoption as sons” (Rom. 8:15). Thus being “led by the Spirit of God,” we are not afraid, but we cry out in faith to our Father in heaven (Rom. 8:14–15). For as we suffer with Christ, the beloved Son, so shall we “also be glorified with him” (Rom. 8:17).
