The Point
One can believe that it is God and God alone that drags the sinner to the cross and to their salvation. However, we, as mankind, have no earthly idea who God has predestined for eternal life and what method of evangelism God has chosen from eternity past to perfect His will. Among all the challenging theological constructs students of the Bible wrestle with, in my opinion, this is a no-brainer. The Bible calls the Christian to share the love of Christ with a lost and dying world AND leave the fruits of that encounter(s) in God's hands.
