Does the Bible Contradict Itself?

[Reforged]

I'm wondering whether there are any biblical passages that contradict one another. Please provide two contradictory passages for discussion and explain why they result in a contradiction. Thanks.

Heres two propositions throughout the Bible in numerous passages that contradict:
1. God is omnipotent, all-powerful and all knowing.
2. We have freewill.

If God has knowledge of events past, future and present then that means there is a single, unchanging path we all travel. Every choice we make is preordained to occur as is the outcome which means it isn't really a choice. We're just following the script of a massive machination.
Ergo, either God is not omnipotent or there is no free-will.
If free-will is implemented then that makes our future unwritten and therefore unpredictable to God, rendering omnipotence meaningless.
If God is omnipotent then that negates freewill, rendering freewill meaningless.
Explain.

Examples:
"And if it is disagreeable in your sight to serve the LORD, choose for yourselves today whom you will serve: whether the gods which your fathers served which were beyond the River, or the gods of the Amorites in whose land you are living; but as for me and my house, we will serve the LORD." (Joshua 24:15)

"For I am God, and there is no other;
I am God, and there is none like me,
declaring the end from the beginning
and from ancient times things not yet done,
saying, "My counsel shall stand,
and I will accomplish all my purpose,"
calling a bird of prey from the east,
the man of my counsel from a far country.
I have spoken, and I will bring it to pass;
I have purposed, and I will do it."
(Isaiah 46.9-11)
