If God, being completely transcendent, says two things, that to us, being limited, finite, creatures, whose reason is corrupted by sin, seem to be mutually exclusive, isn’t it possible that those two things are true, despite our inability to perceive the greater truth? Of course it is possible. It is necessary that we don’t exclude one truth, at the expense of another, simply due to our limited faculties.
That is why, some Christians who affirm God’s sovereignty, and man’s ability to exercise his volition within his nature, are not affirming something wrong. It is merely a more mature understanding of God’s sovereignty, the centrality of Christ, the transcendent holiness of God, the utterly created, finite, and sinful nature of man.
Predestination, and election are not doctrines that are arbitrarily arrived at through implicit inference. They are arrived at from exposition of the explicit teachings of scripture. Contrast the resulting theologies derived from a man centered, (anthropocentric) decisional regeneration, with the more comprehensive God centered (theocentric) sovereign election.
We don’t deny, as some might say, that man makes choices. We just understand that in a compatible, and transcendent way, the sovereign God, ordained those choices in eternity, for His ultimate glory, and our good. The people who ask, “Does God ordain the murdering of a man?” We should reply, “Was that man born without sin? As a sinner, what does he deserve?” The matter of theodicy is all but ignored in this modern age of mediocrity, and ignorance.
We can study the past, and stand on the shoulders of giants, or we can crawl, blindly in the muck, and mire, searching for a morsel of truth, trying to rediscover what was once common knowledge amongst Protestants, while sinners descend to the pit, temporally, and eternally, all around us.
