So why baptism?
Baptism was important back then! No, it did not save anyone from sin nor does It today. Jesus' atoning sacrifice on the cross alone does that! Yet, the Ethiopian demanded it. Peter, Paul and even Jesus instructed believers to make disciples...repenting of sin and being baptized in obedience to the Lord as a sign or public commitment to a new life in Christ. (Acts 2:38, Acts 10:48, Acts 22:16, 1 Peter 3:21, Colossians 2:12, Galatians 3:27, Mark 16:16, Luke 3:21-22, Matthew 28:19-20)
Why do many today not emphasize baptism in regards to fellowship within the Body? I realize, in rare cases, one cannot be baptized. However, it is an act of obedience. It is a witness to a sinful world that "I belong to Christ!"
If it was important to Jesus and the Apostles, it is important to me!
