Answer: Thy kingdom come. That is: So rule us by Thy Word and Spirit that more and more we submit to Thee.[1] Preserve and increase Thy church.[2] Destroy the works of the devil, every power that raises itself against Thee, and every conspiracy against Thy holy Word.[3] Do all this until the fullness of Thy kingdom comes, wherein Thou shalt be all in all.[4]

72. Question: Does this outward washing with water itself wash away sins?

Answer: No, only the blood of Jesus Christ and the Holy Spirit cleanse us from all sins.[1]

[1] Matt. 3:11; I Pet. 3:21; I John 1:7.

73. Question: Why then does the Holy Spirit call baptism the washing of regeneration and the washing away of sins?

Answer: God speaks in this way for a good reason. He wants to teach us that the blood and Spirit of Christ remove our sins just as water takes away dirt from the body.[1] But, even more important, He wants to assure us by this divine pledge and sign that we are as truly cleansed from our sins spiritually as we are bodily washed with

[1] I Cor. 6:11; Rev. 1:5; 7:14. [2] Mark 16:16; Acts 2:38; Rom. 6:3, 4; Gal. 3:27.

74. Question: Should infants, too, be baptized?

Answer: Yes. Infants as well as adults belong to God’s covenant and congregation.[1] Through Christ’s blood the redemption from sin and the Holy Spirit, who works faith, are promised to them no less than to adults.[2] Therefore, by baptism, as sign of the covenant, they must be grafted into the Christian church and distinguished from the children of unbelievers.[3] This was done in the old covenant by circumcision,[4] in place of which baptism was instituted in the new covenant.[5]
