Jesus NEVER excused sin. He forgave it, and said "Go, and sin no more".
Why would we excuse our own?
Is perfection obtainable? No, as we are still in fleshly bodies of imperfection.
Must we be "re-saved"? No, as no one can crucify Christ again.
Must we be brought back into repentance? Yes!!
I am not saying sin is excused.. like no consequence. Jesus commands saved people to follow Him. He rebukes them, disciplines them.. loves them to want them to return to following Him.
That doesn't mean they never go astray. I am sure you have 'gone astray' occasionally in your own walk with Jesus. And I KNOW you wouldn't say that means you weren't one of His sheep to begin with.
I am saying is there is nothing in our walk with Jesus that gets us eternal life to begin with. Jesus still wants us to follow Him of course.
I know ....
The calvinist teaching is the God pre-ordains someone to be converted.. and walk with Jesus and endure to the end. So if the person isn't enduring to the end.. then they weren't pre-ordained.. and aren't saved..
But I can't see this in the bible.
Predestination is either about the fact a place in heaven is pre-set for someone who trust in Jesus as their Saviour.. or about the fact Jesus has pre-set the institution of His churches for a saved person to join.. and these churches have a pre-set destiny in Revelation.
That is predestination.. it's not about predestining some to heaven and some to hell.. and those predestined to heaven will endure to the end!
