The Bible as you know states that Jesus came forward to be baptized. And when John refused to baptize Him Jesus said to him" suffer it to be so now; for thus it beometh us to fulfill all righteousness". The keyword in this statement is all. Jesus did not get baptized to fulfill his own righteousness, otherwise he would be unrighteous before his baptism and we know that was not true. No, Jesus was baptize to fulfill all righteousness. The all righteousness here means he got baptisted for everyone that accepts him. Knowing that all our righteousness is as filthy rags before the Lord. Would not our baptism for ourselfs be a part of that righteousness? It is for this reason that we get baptized into Jesus. Or "in the name of the Father and of the Son and of the Holy Ghost". Both of course are scriptural. Because being baptized in the name of Jesus we are positioned to benefit from Jesus' baptism which was for all believers.
NE apart from faith in him. Christ was offered for all men, but without faith in his sacrifice no man can receive the forgiveness of sins. Man MUST believe IN THE GOSPEL to be actually saved. For the gospel is the POWER unto salvation for the sinner, if he will believe on the Lord Jesus Christ.Romans 1:16
