No. no, no. No free will = partiality. This line by you is as bad as 1 + 1 = 3.
This really is a 'duh' fact my friend,
Your empty explanation is null and void because you believe that God, the Righteous Judge, gives credence to man free-will choosing God, which is, by definition, God being partial to whatever man; furthermore, your Free-willian Philosophy leads to Christ's failure atonement as outlined in the original post.
You believe God trusts your free-will choice, yet it is written "Behold, His servants, He does not trust" (Job 4:18).
I believe that God, the Righteous Judge (Psalm 7:11), gives credence to Lord Jesus, the One Mediator (1 Timothy 2:5), which is, by definition, God being impartial to man; furthermore, I believe in Christ's finished atonement as outlined in the original post.
