Jesus catechizes His disciples in the way of faith by teaching them how to pray. He promises us: “Ask, and it will be given to you; seek, and you will find; knock, and it will be opened to you” (Luke 11:9). If earthly fathers know how to give good gifts to their children, “how much more will the heavenly Father give the Holy Spirit to those who ask him” (Luke 11:13). Thus, father Abraham was bold in his prayer because he believed the gracious promise of the Lord, that he would “surely become a great and mighty nation” (Gen. 18:18). When we pray in Jesus’ name, we also hold “fast to the Head” (Col. 2:19), “rooted and built up in him and established in the faith” (Col. 2:6–7).
