Jesus joined believing with baptism in this verse. An infant doesn't have the ability to believe in Christ. Therefore, such a practice violates the Scriptures. There is not one single command for nor example of infant baptism in the Bible. And to be perfectly honest, immersion is the only scriptural mode of baptism.
Infant baptism is proved false in mode, subjects and purpose.
Arise and be baptized, and wash away the sins, calling on the name of the Lord. If we love the Lord and His word, we will not try to seperate what He has put together. Our desire should be to meekly obey. So many people believe that just any kind or type of worship will be acceptable to God. This passage sets forth the homage that pleases Jehovah.
