I disagree. The bible does teach free will. It may not use those exact words, but it is free will nonetheless.
“I call heaven and earth to record this day against you, that I have set before you life and death, blessing and cursing: therefore choose life, that both thou and thy seed may live.” (Deuteronomy 30:19)
You can not just pick and choose scripture to fit an ideology, I compare and keep scripture in it's context, this is how I know that the notion of free will is not taught in the Bible. You left out the verses before Deu 30:19...
Deu 30:15 See, I have set before thee this day life and good, and death and evil;
Deu 30:16 In that I command thee this day to love the LORD thy God, to walk in his ways, and to keep his commandments and his statutes and his judgments, that thou mayest live and multiply: and the LORD thy God shall bless thee in the land whither thou goest to possess it.
Deu 30:17
But if thine heart turn away, so that thou wilt not hear, but shalt be drawn away, and worship other gods, and serve them;
Deu 30:18 I denounce unto you this day, that ye shall surely perish, and that ye shall not prolong your days upon the land, whither thou passest over Jordan to go to possess it.
“And if it seem evil unto you to serve the LORD, choose you this day whom ye will serve; whether the gods which your fathers served that were on the other side of the flood, or the gods of the Amorites, in whose land ye dwell: but as for me and my house, we will serve the LORD.” (Joshua 24:15)
In this verse Joshua was telling them to choose between the false gods because they were not serving the Lord.
“Envy thou not the oppressor, and choose none of his ways.” (Proverbs 3:31)
I did say we were commanded to choose, just not 'able' to do so without the Lord changing us first.
“Therefore to him that knoweth to do good, and doeth it not, to him it is sin.” (James 4:17)
Again, taken out of context. This verse is about those who are already believers but do not keep the law. If you read the whole passage you will see it was talking about judging your brother(another believer). This verse was saying that if someone is your brother in Christ then he knows what is sin and knows what he should and should not do.
God gives us the leeway to choose our own path in this life. It is up to us to choose to walk his path.
If it was up to us then no one would be saved. Not by works are we saved lest any should boast. Choosing is an act, an act is a work, thus choosing is not what brings salvation.
Like I said, we are told to choose, but we do not have the ability to do so because we are dead in sin and our hearts are wicked. Until the Lord changes our hearts, we can not choose the things of the Lord. If it was up to us to choose without the Lord first changing us, then the glory of salvation would not be the Lord's but rather our's, all the work and credit would be our's and not the Lord's. However, we know that salvation does not come due to anything we do, including 'choosing'.
