Brother,
There are many things in the Word that are black and white. You can find these answers in the Word such as...
1. Is it ok to get drunk?
2. Is it ok to have sex before marriage?
3. Is it ok to steal?
These and many more are black and white in the Word.
The things that are not black and white I believe are under the realm of Faith. Faith comes hearing God's Word thus having a relationship with Him.
Put God first my friend and eerything else will work out.
Matthew
6:32 (
For after all these things do the Gentiles seek
for your heavenly Father knoweth that ye have need of all these things.
6:33 But seek ye first the kingdom of God, and his righteousness; and all these things shall be added unto you.
As far as the term free will ...I believe that might be a baptist term. I don't know. I don't use that word much.

God bless
