The Preaching of Repentance Prepares Us for the Coming of the Lord
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 Ministry of the Gospel of Christ Jesus, Her Savior
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 Lord Jesus Is with His Church in the Apostolic Ministry of the Gospel
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)
Jesus Christ Is the True Vine Who Bears Much Fruit in Us
“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).
Jesus Is Lifted Up on the Cross so that We May Look to Him and Live
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).
