If you have only been christened as a baby, you have been deceived. You have not been baptized at all. Sprinkling and pouring are valid forms of baptism. The context also makes this clear. Baptism requires much water.
Baptism is an immersion, a burial in water.
If you have never been immersed, you have been deceived. You have not experienced Christian baptism at all. Because we are commanded to be baptized for the remission of sins. Listen to what happened on the Day of Pentecost. Many people refuse to obey this simple command because they have believed another lie, namely, that one is saved by faith only.
