Predestination and election are difficult to understand until we diligently consider the context — the dreadfully sinful human condition: Man’s Depravity. Apart from carefully integrating this concept throughout our theology, many fundamental precepts of Scripture appear hopelessly irreconcilable.
For example, how can God choose who will be saved while respecting Man’s Free Will? Similarly, How can a loving God be in total control when there’s so much evil and suffering? These are perhaps the hardest questions, and they aren’t peripheral; they’re fundamental spiritual bedrock. We can’t afford to dismiss them, yet resolving such mysteries seems impossible. Many stumble here, and go no further.
Yet God Himself gives us the key by addressing the problem directly, asking these same questions, and then answering them. God’s purpose in election will be realized (Ro 9:11) yet God will be totally righteous in it all (14), because God’s not obligated to be merciful (15) — by definition: mercy is undeserved, never justly required.
The reality is, if God didn’t elect anyone, choose anyone to be saved, and He let us all go our own way — we would: every last one of us would walk away from Him; we would not come to Him. (Mt 22:3) This would be fair, certainly, but then Heaven would be desolate (Lk 14:16-18a), and the world filled with even more evil and suffering than it already is. (Ge 6:5) This is what Depravity teaches us (11), if we listen. (Je 17:9)
So, if God chooses to intervene in a few of us, choosing us out from the masses and giving us new hearts and new wills that don’t run away, He’s showing mercy in election, not being unjust.
God never actually turns anyone away who seeks Him, or causes anyone to do evil; He controls by mercifully restraining us from acting out our full evil nature according to His sovereign purposes. (2Th 2:7) There’s nothing at all inappropriate about restraining evil; so, God’s in absolute control of all that happens (Ep 1:11), yet He’s also perfectly good, just and merciful; He’s righteous and holy in all He does. (Ps 145:17)
In giving us new hearts God doesn’t force us against our will; what He does in His elect is heal our will, displacing our love of lies, which moved us to distrust and despise Him, with a love for truth; He works in us to will according to His good pleasure (Php 2:13), such that we begin to want to do good. He works all this in us for our good and for His glory. (Ro 8:28)
The only remaining challenge here is: Why doesn’t God save everyone if He has this ability? The answer lies in God’s glory: He’s most glorified in fully revealing His nature, His wrath and power as well as His love and mercy. (Ro 9:22-23) If God didn’t let most all of His enemies act like enemies, and treat them as He does, we’d know much less about Him, so that’s exactly what He’s doing; God is perfectly revealing and glorifying Himself by only saving a few. (Re 15:3)
Rather than faulting God for being absolutely sovereign, and for choosing only a remnant to be saved, we ought to let all the blame for evil lie where it truly belongs: with sinful Man, and glorify God for His mercy. (Ro 15:9) Rather than complaining and running away, we seek God until we find Him (He 11:6), and discover that we’re indeed elect, vessels of divine mercy. (Ro 9:23)
And in being vessels of infinite mercy (Ps 103:11), undeserving recipients of God’s kindness, love and favor, we also ought to be merciful (Lk 6:36), to be compassionate toward those who are out of the way (He 5:2), esteeming others better than ourselves. (Php 2:3)
