Grace is a gift freely given and there is sufficient Grace that all might be saved, yet all are not saved. But Grace, like sin requires cooperation to be effective. That is the purpose behind the free will and the knowledge of the difference good and evil given us by God. It is what makes us in His image and what differentiates us from the soul-less animals. Unlike sin, which often requires we do nothing at all to cooperate with it, Grace requires an affirmative act of the will. Foreknowledge is not predestination.
Read the Bible, all of it. Perhaps your Salvation will be found in part, in the missing seven books. Peace be with you.
Do you cooperate by your own ability or is it the Holy Spirit who enables your cooperation?
Scam.
