Jesus said, “those who believe in Me will live even if they die“! This is what makes it so hard for some people to become Christians. Not because it is so easy when you feel His touch on your heart and soul, but because they believe that they need to help Him in their salvation!
There is nothing that you can add to His sacrifice which will help in any way to bring salvation to yourself. Just believe in Him and what He did for you, then determine that you will live for Him and leave your old way of life behind. Some people may see that as a hard thing to do, but if you compare living for Him in this life to an eternity without God in hell I think that putting up with being a Christian is a much better way to live!
God sent Jesus to the Earth so that we could come to know Him and be saved from our own sinful ways. But if your heart hasn’t changed and your life has stayed the same as it was before, did you really accept Him as your Savior or did you just say a few words and get wet in the baptistry?
Please, seek Jesus for your salvation before your life is over because there are no second chances after you die.
