Ha! Good movie! But no, I was thinking of Huck Finn going swimming.
Sometimes people are baptized “into the Southside Baptist Church” or “into the First Methodist Church of Smallville”, etc. Other people are baptized “as a public demonstration” of sorts.
But is that what you see when you read the Bible? Or do you find people being baptized “into Christ”, “into remission of sins”, etc? Without the instructions from God, does baptism do anything except get you wet?
