Baptism is an earthly sign from our heavenly King. In baptism, our Triune God says, “You are my covenant child. Let there be no doubt. You are my chosen race, holy nation, and royal priesthood.” But how can we be sure about this sign from heaven? Peter tells us that baptism comes to us by the resurrection of Jesus Christ who is gone into heaven, angels and authorities and powers being made subject unto him. The One who speaks this sign to us is the same One who has delivered His people through water time and time again, be it Noah through the flood, Israel through the sea, or our Lord Himself who has passed through the water above the heavens. God speaks from His temple through water today, saying, “I am your God, you are my people.”
