Acts 2:38
38Peter said to them, "(
A)Repent, and each of you be (
B)baptized in the name of Jesus Christ
for the forgiveness of your sins; and you will receive the gift of the Holy Spirit.
39"For (
C)the promise is for you
and your children and for all who are (
D)far off, as many as the Lord our God will call to Himself."
Acts 22:16
16'Now why do you delay? (
A)
Get up and be baptized, and (B)wash away your sins, (C)calling on His name.'
Col 2:11-12
11and in Him (
AA)you were also circumcised with a circumcision made without hands, in the removal of (
AB)the body of the flesh by the circumcision of Christ;
12having been (
AC)buried with Him in baptism, in which you were also (
AD)raised up with Him through faith in the working of God, who (
AE)raised Him from the dead.
Here, her point was that since baptism replaces circumcision, and newborn babies were circumsized, then the promise of baptism is for infants as well.. not only for adults. That any faith anyone has is the gift of God.
