God's sovereign election and man's exercise of responsibility in choosing Jesus Christ seem opposite and irreconcilable truths - and from our limited perspective they are opposite and irreconcilable. That is why so many earnest, well-meaning Christians throughout the history of the church have floundered trying to reconcile them. Since the problem cannot be resolved by our finite minds, the result is always to compromise one truth in favor of the other or to weaken both by trying to take a position somewhere between them. We should let the antimony remain, believing both truths completely and leaving the harmonizing of them to God.
John MacArthur
