Sea Breeze said "Before the cross, Jesus predicted that he would resurrect himself from the dead, while he was dead."
No, he did not predict that. There was no cross. Jesus did not predict that he would resurrect himself, because he would be dead.
"So, if you are good with a man who resurrected himself from the dead being the Lord of your life, that's about all there is to getting saved. Living the Christian life is a 3 step process though.
1. Justification
2. Sanctification
3. Glorification"
None of those 3 are part of Christianity. What ever happened to "I will cause a boy who drives a plow to know more of the scriptures than the pope."
No one needs to know those 3 words listed above.
