We are accustomed to think of baptism as a marker of our testimony. By it we declare our allegiance to Christ, and our intention to live before Him as sincere Christians. This is quite true, and it is particularly in evidence when we baptize someone on the basis of his profession of faith. He was not a believer, but God saved him from a corrupt generation, and so he confesses his faith at his baptism. This is right and proper and good. But baptism is also God’s testimony, which is more in evidence when we baptize an infant. We are not the only ones who speak in a baptism. There is human confession, true enough. But there is also divine declaration. “And I will take you to me for a people, and I will be to you a God: and ye shall know that I am the Lord your God” (Exodus 6:7). In baptism, God makes a declaration about His covenant, and about children’s children. God called my parents out of unbelief, and here we are, five generations later, with thousands of generations yet to go (Deut. 5:10; 7:9).
