Hell if I know. I see two ways around it (mind you, I'm not a believer). First option is that "omniscience" means knowing all possible outcomes. That one is ****ty, because omniscience means something else entirely, especially from the Christian perspective. The second is that a being with omniscience does not affect one's free will. Let's say you are suddenly gifted with omniscience. Does your foreknowledge of my typing out this post mean that I didn't choose to type it? Is my choice less real simply because you know the outcome? I happen to not think so, personally. But hey, that's me.
I can tell you were raised Catholic. There's some guy out there. Led a pretty big movement. I think his name was Martin Luther. Look him up.
Oh, there's another one too, his name was Yeshua or something like that. He had something to say about that too
See the above. TYTT wasn't trying to convince you of anything, he was trying to show you the biblical Christian perspective, which is in opposition to the idolatrous Roman one
I like this one better:
Matthew 7:21-23
21 Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven.
22 Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works?
23 And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.
Note that God's will, from the Christian perspective, is not works, Gene.
