There is no "free will" to accept Christ or reject Him. Each and every man has already been dealt with by God and locked into a destiny BEFORE He created heaven, earth, and man.
God gave human the ability to choose, decide.
A volition.
Without volition, Adam's sin would not have happened.
Nor can there be noble love (agape) that kept our Lord on the cross while He could have turned His torturer inside out at the sub-atomic level.
We make decisions every day, big and small.
We can choose to believe or not to believe.
We can choose to trust people or not to trust them.
We can even choose not to believe that we have the ability to choose.
But know this, by doing so we are exercising the very thing we deny.
God pre-knew who will be saved, this is correct for He knows everything.
Beyond that, He is Knowledge.
But don't confuse that with God forcing it upon His creations to have a relationship with Him.
God grow us by the role of His Holy Spirit as the teacher, guide, and enlightening agent for those who chose Him over self.
And the realization that self needs redemption is the most beautiful thing that can happen to anyone who hears the Gospel.
Notice that choosing God does not grant us merit. No more than a drowning person who chose to grab the life-saver and be saved. In no shape or form he would then brag about his "choosing" as the cause of his salvation. A soften heart is a Spirit-opened heart that is grateful to the Savior. A heart that from that moment on, started to fall in love with the attractive Lord he discovered.
Without volition, the plan of salvation is not as beautiful, genius, majestic, and out of this world; not unlike the Supreme Being who conceived it.
