The contradiction is in saying "we are chosen", yet turning around and saying we are the ones who chose. Which is it?
I don't see a contradiction. If you do please explain to me.
From the Scriptures
But as many as received Him, to them He gave the right to become children of God, even to those who believe in His name, who were born, not of blood nor of the will of the flesh nor of the will of man, but of God.
John 1:12-13
Takes free will to receive Him
The last part of your verse tells us that those who believe did so not by their will, but by God's will. It actually argues against free-will.
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 24:15-16
I share the next part of Joshua 24, which reveals the false belief of Israel that they could somehow obey God’s command so well that God would be pleased. Joshua warns them that their thinking they could please God by their works will end up badly.
Do you recall the history of Israel and how they never gave up their idols?
Joshua 24 is a warning to us that we can never please God with our choices.
Joshua 24:16,19-21
[16]The people replied, “We would never abandon the lord and serve other gods.
[19]Then Joshua warned the people, “You are not able to serve the lord, for he is a holy and jealous God. He will not forgive your rebellion and your sins.
[20]If you abandon the lord and serve other gods, he will turn against you and destroy you, even though he has been so good to you.”
[21]But the people answered Joshua, “No, we will serve the lord!”
I call heaven and earth to witness against you today, that I have set before you life and death, the blessing and the curse. So choose life in order that you may live, you and your descendants,
Deuteronomy 30:19 -
This verse has nothing to do with eternal salvation, but it has to do with blessing in the land while the people were alive.
Choice is an act of the will. We use free choice every day. Scripture says we "choose" life or death
You have developed a philosophy of free-will by looking for a few verses, without context, to serve as a prooftext for your philosophy. This is always the case when a person claims there is free-will in regard to their salvation.
Now, we do make decisions as to daily life here on earth. Each decision is by God's ordained will, meaning God gives a "yes" to our decisions...even the evil ones. This is because God is great in mercy and patience.
We have no say, however, in our being adopted by God. We have no say in being made alive in Christ. Dead men can't choose.
I point out that from Genesis to Revelation we see God choosing to extend grace and give the gift of faith. God chose to call out Adam and Eve while they ran to hide. God chose Abraham from all others. God chose Jacob and rejected Esau. God chose Moses. God chose the judges. God chose David (notice that the people's choice, Saul, was a failure). God chose the prophets. God chose John the Baptist. Read John's Gospel and notice how God chooses who will be His sheep. Read Paul's letters and Peter's letters and look for the words chosen and predestined. Just read and let God's word speak. If you put aside your presupposition and philosophy and just let the Bible speak for itself, you will find your free-will argument withered to nothing. That's what happened with me. I grew up as a Mennonite. It's hard to be more free-will than Mennonites. But, I started reading my Bible and I just let it say what it says. I came to see that it is all God and nothing from me when it comes to me being adopted by God. God, for some unknown reason (to me) chose to adopt a person who was born in rebellion and was living in rebellion. There was no reason to choose me. But, God decided to be gracious and merciful and cleanse me by the atoning work of Jesus.
When I let go of the philosophy of free-will, I was set free from my burdens that I had built for myself. Joy in Christ is so easy. Gratitude flows because of God's amazing grace.
