I don't know if I understand very well your specific question. Maybe those scriptures can help. If not, please just ignore my post.
Mk. 16.15 And he said unto them, Go ye into all the world, and preach the gospel to every creature. 16.16 He that believeth and is baptized shall be saved; but he that believeth not shall be damned.
Lu. 24.45 Then opened he their understanding, that they might understand the scriptures, 24.46 And said unto them, Thus it is written, and thus it behoved Christ to suffer, and to rise from the dead the third day: 24.47 And that repentance and remission of sins should be preached in his name among all nations, beginning at Jerusalem. 24.48 And ye are witnesses of these things.
Act. 2.41 Then they that gladly received his word were baptized: and the same day there were added unto them about three thousand souls.
Act. 8.36 And as they went on their way, they came unto a certain water: and the eunuch said, See, here is water; what doth hinder me to be baptized? 8.37 And Philip said, If thou believest with all thine heart, thou mayest. And he answered and said, I believe that Jesus Christ is the Son of God. 8.38 And he commanded the chariot to stand still: and they went down both into the water, both Philip and the eunuch; and he baptized him.
[FONT="]Act. 10.47 Can any man forbid water, that these should not be baptized, which have received the Holy Ghost as well as we? 10.48 And he commanded them to be baptized in the name of the Lord. Then prayed they him to tarry certain days.
[/FONT]Act. 18.8 And Crispus, the chief ruler of the synagogue, believed on the Lord with all his house; and many of the Corinthians hearing believed, and were baptized.
