If God did give everyone an equal chance and woos everyone the same, then why do some respond positively? Are they better than others? Do they have more inherent virtue? Faith is not a work and therefore non-meritorious. The Bible teaches that faith is a gift and not something we conjure up ("Faith comes by hearing, and hearing by the Word of God," according to Rom. 10:17).
We are elected unto faith, not because of faith.
This is the so-called prescient view that God just sees ahead who will believe and chooses them. However, the election is unconditional, and not because we deserve it--we are in no superior or more virtuous than others who don't happen to believe because it is grace all the way. If mercy is deserved, it is no longer mercy, but justice. Jesus said that we are unable to come to Him and only when the Father "draws" us ("No one can come to me unless the Father who sent me draws him...") can we respond to the gospel message (cf. John 6:44; 65).
Sometimes the gospel falls on deaf ears because God hasn't worked in their hearts to prepare them. We do naught to prepare ourselves unto salvation. There is an inward call of God and a general call that we do by preaching. Then who believe? "The elect attained unto it, and the rest were hardened," says Rom. 11:7. Acts 13:48 declares, "As many as were appointed unto eternal life believed." According to Rom. 8:30, everyone whom God calls gets saved. Left alone, none of us would've chosen Christ. We love Him because He first loved us. "No one seeks for God," says Romans 3:11. Soli Deo Gloria!
