In reference to Salvation:
I believe “Prevenient Grace” is the best way to harmonize what Scripture says as whole in regards to God’s Sovereignty and Man’s Free Will. Prevenient Grace is the belief that God draws men at certain times to see and understand the gospel so as to choose it or reject it of their own free will. Without this illumination or drawing by God, a person cannot understand the gospel. For in the Parable in the Sower, we learn that the first seed did not even understand the gospel message. The devil stole the seed out of their heart before they could understand it. So there are times where a person can hear the gospel and not understand it because they have not been drawn by God yet. But God will draw all men unto Him in His timing, though.
