Acts 22:16
And now why tarriest thou? arise, and be baptized, and wash away thy sins, calling on the name of the Lord.
I dont see another concept presented here to wash away sins, but to be baptized. If I was on the receiving end of that statement, I would have equated baptism with my sins being washed away. (you know..WATER(baptized)....WASH, (I kinda see it like that), just most folks use water to wash stuff, but what do I know?, maybe baptism is like a "waterless car wash"...LOL....respectfully
Brother, look at the passage again...Arise>Baptized(water)>WASH(water) AWAY THY SINS,,,,Brother, this is clean as a whistle. How my brother, can you not see that?(now that is directly contextual)
I dare you to try to "wash" the dishes tonight without water. Or take a bath for that matter.
There is more than one reason that water baptism is
COMMANDED my brother.
