Jesus and His disciples came baptizing.
Jesus never water baptized anyone His entire ministry....So, if water is essential for forgiveness or regarding going to heaven, i guess he kinda forgot on the way to being the "no man comes to the Father but by Me". John 14:6
Also,
Paul, the apostle who wrote most of the New Testament, and is responsible for delivering the "Gospel of the Grace of God" to the world, originally, said......."Christ sent me not to water baptize".
