You are not properly in touch with doctrinal terminology, DrE.
"Prevenient grace" is God's grace that comes prior to salvation to everyone. (Prevenient mean "comes before".)
See Acts 14, Romans 1 & 2, etc.
It is all the kindnesses, all the goodness, all the drawing/wooing, of God that are granted all of us prior to salvation.
I will point out to you that the word "Trinity" also does not appear in scripture. Nonetheless, it is a legitimate biblical teaching.
LOL. I thank God I am not "in touch" with the distortions of John Wesley and his concocted "prevenient" grace. The very idea demeans God's grace which is perfect, absolute, particular, irresistible and determinant.
Thank God.
And BTW, no Calvinist believes in "prevenient" grace. It is a word and concept created and utilized by Arminians.
"...The Scriptures testify that the man without the Spirit cannot understand the things of God (1 Cor 2:14). Even with prevenient grace theoretically putting humanity in a neutral position, we would still lack the quickening Spirit to give us what we need. How is it then that the natural man can understand or desire God independent of grace? Can a blind man see prior to his eyes being opened? Can a man with a heart of stone love and desire God before His heart is made flesh? How can a ox desire flesh to eat or water rise above its source? We believe that salvation is of the Lord from beginning to end. He deserves all the glory. While we were still helpless Christ died for us and His death purchased everything we need to be saved, including our regeneration. For an unregenerate man would not ever desire the things of God on his own. If God's grace does not save us then man still ultimately decides based on some principle within, either good or evil."
Same old, same old.
