What does scripture say about Baptism?
“Do you not know that all of us who have been baptized into Christ Jesus were baptized into his death? We were buried therefore with him by baptism into death, in order that, just as Christ was raised from the dead by the glory of the Father, we too might walk in newness of life. For if we have been united with him in a death like his, we shall certainly be united with him in a resurrection like his.” Romans 6:3-5
Romans 6 says that baptism makes us participants in the death of Christ, so that we might ‘walk in newness of life’ and share in resurrection.
“But when the goodness and loving kindness of God our Savior appeared, he saved us, not because of works done by us in righteousness, but according to his own mercy, by the washing of regeneration and renewal of the Holy Spirit, whom he poured out on us richly through Jesus Christ our Savior, so that being justified by his grace we might become heirs according to the hope of eternal life.” Titus 3:4-5
Titus chapter 3 says that Christ saves us not by works of our own righteousness, but by ‘the washing of regeneration,’ that we are justified by grace and come to possess the hope of eternal life.
“In him also you were circumcised with a circumcision made without hands, by putting off the body of the flesh, by the circumcision of Christ, having been buried with him in baptism, in which you were also raised with him through faith in the powerful working of God, who raised him from the dead. And you, who were dead in your trespasses and the uncircumcision of your flesh, God made alive together with him, having forgiven us all our trespasses, by canceling the record of debt that stood against us with its legal demands. This he set aside, nailing it to the cross.” Colossians 2:11-5
Colossians chapter 2 says that baptism corresponds to the circumcision of the Old Testament. This indicates that baptism can be given to children. Also Colossians 2 says that baptism brings about the forgiveness of sins.
“…God’s patience waited in the days of Noah, while the ark was being prepared, in which a few, that is, eight persons, were brought safely through water. Baptism, which corresponds to this, now saves you, not as a removal of dirt from the body but as an appeal to God for a good conscience, through the resurrection of Jesus Christ, who has gone into heaven and is at the right hand of God, with angels, authorities, and powers having been subjected to him.” 1 Peter 3:20-22
