Almighty and eternal God, according to Your strict judgment You condemned the unbelieving world through the flood, yet according to Your great mercy You preserved believing Noah and his family, eight souls in all. You drowned hard-hearted Pharaoh and all his host in the Red Sea, yet led Your people Israel through the water on dry ground, prefiguring this washing of Your Holy Baptism. Through the Baptism in the Jordan of Your beloved Son, our Lord Jesus Christ, You sanctified and instituted all waters to be a blessed flood, and a lavish washing away of sin. We pray that You would behold (name) according to Your boundless mercy and bless him with true faith by the Holy Spirit that through this saving flood all sin in him which has been inherited from Adam and which he himself has committed since would be drowned and die. Grant that he be kept safe and secure in the holy ark of the Christian Church, being separated from the multitude of unbelievers and serving Your name at all times with a fervent spirit and a joyful hope, so that, with all believers in Your promise, he would be declared worthy of eternal life, through Jesus Christ, our Lord.

–Martin Luther (Flood Baptism Prayer)
