THEN we are able to comprehend what only the saints of God can comprehend. The veil keeps you away from eternity, from a Garden of revelation and mystery so precious that God preserved it in Himself until Christ should come, leaving entire ages outside the opportunity to know it. THEN the truth floods in. When the veil ripped, Jesus died. Now, we also know that a Christian is one who has died, been buried and risen with Jesus.
Burial occurs after death.
So true baptism only is valid after we truly commend our spirits to God. After we really get our hearts into it. And Philip said, If thou believest with all thine heart, thou mayest. And he answered and said, I believe that Jesus Christ is the Son of God. Believing with all our hearts is more than just casual belief and understanding and agreement.
