Q. Does this outward washing with water itself wash away sins?
A. No, only the blood of Jesus Christ and the Holy Spirit cleanse us from all sins.
 Mat.3:11; 1Pet.3:21; 1Jn.1:7.
Q. Why then does the Holy Spirit call baptism the washing of regeneration and the washing away of sins?
A. God speaks in this way for a good reason. He wants to teach us that the blood and Spirit of Christ remove our sins just as water takes away dirt from the body. But, even more important, He wants to assure us by this divine pledge and sign that we are as truly cleansed from our sins spiritually as we are bodily washed with water.
 1Cor.6:11; Rev.1:5; 7:14.  Mk.16:16; Act.2:38; Rom.6:3-4; Gal.3:27.
