The Bible teaches predestination and the unconditional election of God. God is sovereign in salvation. The Bible also tells us to trust in Jesus, assuming free will.
We hold to both predestination and free will. We do not logically reconcile them but accept them both as true and wait on understanding more in heaven.
We challenge people to believe in Jesus. But we pray to God to open their eyes and give them faith, and we give Him all the credit if they do turn to Jesus. (See Romans 8:28-29, 9-11, Ephesians 1:3-14, John 6:44.)
