I know one thing about 1Cor 4 and it's something you personally HATE: God makes the difference either directly or indirectly through secondary causes. God has
given to his elect by
His grace (divine POWER) everything they need for salvation (
2Pet 1:3-4). All of God's good and perfect gifts come from above (
Jas 1:17). This is how Paul could ask that rhetorical question in
1Cor 4:7 by asking WHO makes the difference!? If you think you can make the case that Paul's answer is MAN makes all the difference in the world, then make your case! But just remember, it's ultimately NOT by man's doing that anyone is in Christ Jesus but by God's (
1Cor 1:30). But you falsely believe that it's man's will that puts everyone in Christ, don't you? You essentially said earlier that man's will was the
ultimate reason which is totally illogical and unbiblical. You assign the final cause in the chain of salvation to man's "freewill" choice, when that particular cause is but
one of many secondary causes. The ultimate cause is God (see
Rom 8:29-30).
