Answer
Certainly, since God knows everything, it would have been possible for God to base His predestination and election of individuals upon His foreknowledge of the future. In fact, that is the exact position that many Christians believe, as it is the Arminian view of predestination. The problem is that it really is not what the Bible teaches about predestination, election, and foreknowledge. In order to understand why the view that “God made His choice based on merely knowing the future” is not what the Bible teaches, let’s first consider the passages that speak into the tension (but not irreconcilable tension) between predestination, election, and foreknowledge.
Ephesians 1:5 tells us that God “predestined us to be adopted as his sons through Jesus Christ, in accordance with his pleasure and will.” According to this verse, the basis of our being predestined is not something that we do or will do, but is based solely on God in accordance with His good will and pleasure.
In Ephesians 1:11 we see that people are “chosen, having been predestined according to the plan of him who works out everything in conformity with the purpose of his will.” From these and many other passages, we see that Scripture consistently teaches that predestination or election is not based upon something that we do or will do. God predestined people based on His own sovereign will to redeem for Himself people from every tribe, tongue, and nation. God predetermined or predestined this from before the foundation of the world «according as he hath chosen us in him before the foundation of the world, that we should be holy and without blame before him in love: », (Ephesians 1:4) based solely on His sovereign will and not because of anything that He knew the people would do.
But what about Romans 8:29 where it says that those “He forE knew, “He also predestined”? Doesn’t that imply that predestination is based on God’s foreknowledge? Indeed, it does teach that predestination is based on God’s foreknowledge. However, God’s foreknowledge, knowing things or events before they occur, is not the sole basis for predestination. We understand that His will and pleasure are also factors. While God’s foreknowledge and predestination demonstrate His sovereignty, the Bible also teaches that individuals are responsible for their choices (Joshua 24:14-15; Luke 10:42; Hebrews 11:24-25). The real question is not whether God knows who will believe, but why some believe while others do not. God’s desire is for all to be saved and come to repentance, as stated in 1 Timothy 2:4 and 2 Peter 3:9. He extends salvation to everyone, as Titus 2:11 affirms, yet we recognize that not everyone will be saved.
The following quote by John Murray addresses this issue effectively: “Even if it were granted that ‘foreknew’ means the foresight of faith, the biblical doctrine of sovereign election is not thereby eliminated or disproven. It is indeed true that God foresees faith; He foresees all that comes to pass. The question then becomes: where does this faith, which God foresees, originate? The only biblical answer is that the faith God foresees is the faith He Himself creates (cf: John 3:3-8; 6:44, 45, 65; Ephesians 2:8; Philippians 1:29; 2 Peter 1:2).). Hence, His eternal foresight of faith is preconditioned by His decree to generate this faith in those whom He foresees as believing.”
