Water baptism is to be administered only by immersion.
*Paul said, "We are buried with him [Jesus Christ] by baptism" Romans 6:4; Colossians 2:12.
*Jesus came up "out of the water" Mark 1:10.
*Philip and the eunuch went down "into the water" and came up "out of the water" Acts 8:38-39.

Jesus' death, burial, and resurrection are applied to our lives when we experience New Testament salvation: "Repent [death to sin], and be baptized [burial] every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost [resurrection]." Acts 2:38; Romans 6:1-7; 8:2
