It's not a religion - or at least it shouldn't be. It's about a relationship with the Lord Jesus Christ.
Don't let people turn you off from Christianity. People are human. They make mistakes. They sin.
What you need to know: John 3:16...
For God so loved the world that He gave His only begotten Son that who-so-ever believes in Him shall have everlasting life.
What's it all mean?
There's no sinner's prayer... There's just you saying: "God, I believe in You. I believe that Jesus came to earth, died on a cross, and rose from the grave three days later. I believe that He died so that I can live."
That's it. If you truly believe in that - if you can truly accept Jesus the Christ as YOUR Lord and Savior. You will go to heaven.
If you want more information or to discuss this I'd love to hear from you!
