The will is saved by grace from it's bondage to sin which makes it free to decide for itself whether it will believe the truth presented or not.
No! More doublespeak. The will is potentially saved by ineffective grace from its bondage to sin. If the will were truly saved, then all mankind would be saved from the penalty, power and presence of sin. In your wonky scheme of salvation Christ doesn't actually set anyone free, as He promised; rather, he provides everyone with the opportunity to be set free. But Jesus never said that whoever the Son provides an opportunity to be set free will indeed be free if they choose to be.
To what should we liken your unbiblical concept of synergistic salvation from bondage? In your world Christ is a good-intentioned, compassionate but delusional warden in a prison who offers to set long term prisoners free. He gives each prisoner a key to his prison cell and tells them all they have to do is insert their key into the cell lock, turn it and walk out free people. Of course, the vast majority of long-term prisoners will opt to remain behind bars because they have become so accustomed (addicted) to their highly structured lifestyle over the years (3 hots, a cot, clothing on their backs, roof over their heads, work routines, etc.) that they opt to remain prisoners since that is all they know. In this scenario, the warden doesn't save anyone since He was not the one who actually frees them. The ones who opt to leave save themselves by their "freewill" decision to fly the coop. BY THEIR DOING, they walk free. All the warden did was make it possible.
But is this how the ancient Hebrews were set free from their bondage to Pharaoh? God merely made it possible for the Hebrews to leave Egypt? Is this your idea of rescuing grace!? God's power in Egypt was ineffectual?
