My husband, who is not a fan of the beach much anyway, prefers to gradually make his way into the surf, letting his body adjust bit by bit. Some people who enter the water this way prefer it because it allows them to escape getting completely wet, while with my way there is no way to prevent being soaked from head to toe.
There is no "better" way to enter the surf. However, when it comes to our spiritual life, there is no such thing as a slow progression into Christ.
Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new," (2 Corinthians 5:17.) The old person we were was crucified with Christ and we are raised a new creature. So lovely is the new creature we have become Paul says it is "created in righteousness and true holiness."
We have not been merely dipped, part by part into our Lord. We have been totally immersed, dived into Him. We have not been changed just a little, we have been totally transformed and raised again. Because of this, it is incumbent upon us to walk as those that are alive from the dead.
