What's funny when I see these debates are the questions. When you say "Do you see Jesus as the sin bearer", you may was well ask "Do you believe I Peter where it says "He bore our sins....", or Isaiah 53 where it says the same".
You do what you like, but it's SUCH A WASTE OF TIME debating anyone but orthodox, yes they did it in the old days, but they didn't have the information we have today. It's clear Jesus died only for His sheep, for the elect, I don't see Hitler sinless do you, not Hitlers sins judged twice, it's insanity.
Was watching on YouTube "Abraham, Isaac and Jacob" (We need some better English versions), not a verse goes by without showing God's full sovereignty over all affairs of man "I prevented Abimilech from sinning against you", "The Lord put into her heart to get the servant water", "She was barren, but the Lord blessed her and she was with child", I think we have to look at it this way;
Atheists, who have not the Spirit read it, and see nothing. Arminians read it and see nothing. I think we must be most charitable to the new Christian, or the Arminian who is new to the "debate, there is no debate", so how can they miss it? "The natural man cannot understand the things of God". Abraham wasn't a good man, he was a pagan, it's God that called him and made him into what he was, same with Isaac and Jacob. Each and every action ordered by the Lord, JUST AS HE'S SAID.
Really you're wasting your time, these people have their own philosophy, maybe they were raised that way, maybe they won't exercise Faith and believe what God says about Himself, and maybe they are one of the "Lord Lord didn't we do this and that in your name", "I never knew you", but it's ridiculous, read Job, read Isaiah, well if you believe in free will don't for you can't trust scripture if man has free will, God DIDN'T put the words in their mouths. It's just a joke, a decade, over a decade is long enough, I've done my duty, you'll find some really don't know the Lord, but again ALWAYS give the charity that they do, and are just very confused.
