Go to learn about how to be forgiven for your sin, and to pass from death (because of sin) to life (eternal life, spiritual life).
Christianity is not a religion. It's a relationship with Jesus Christ. In that relationship, He changes you in a way other things can't change you. He changes your insides, your heart, your mind, understanding, outlook, viewpoint, focus. He breathes life into your existence, making all things new.
It is the born again nature, a down payment of the full promise of eternal life. Its presence electrifies your existence, so amazibg that until it happens you can't believe it until it happens to you.
Best regards, Rick C. Hodgin
