I can;t give you a passage of scripture which says water baptism is for remmision of sin anywhere. So why would it matter of it is shown in the OT.
As in the OT. Water baptism is a prefigure of what really saves, the washing of the HS.
Arron and his sons were washed in the jordan by moses, a symbol of what God would do for us after the death of Christ.
No my friend, It says God baptized me into Christ. Man can not baptize me into Christ only God does.
It is a huge assumption that the word baptize means in water, It does not always mean water, the thing we are babptized into is shown in romans 6. The death and burial of Christ.
Not water.
If you want to be baptized in water, Feel free. I did in obedience to the command of Christ,
But I will never base my salvation on an immersion in water, I will base it and trust god because he himself baptized me into the death, burial and body of Christ
Thats why I KNOW I am saved, it is not based on my work, but Gods completed work, on the cross. and in my life. It is not a defiled salvation, it is a pure salvation. completed fact.
