Wow! Talk about DOUBLESPEAK! "IF they exercise that efficacy to repent..."??? This is analogous to saying that if Lazarus hadn't exercised the efficacy of Christ's grace when He commanded to him to come forth, Jesus would have failed to raise him from the dead.

This is just your clever way of framing what I have long maintained about you FWers: At the end of the day, all true efficacy is bound up in man's "freewill". It's not God's grace or power that finally saves; it's man's volition that he must exercise to effectuate his own salvation!
Also, there is no passage in scripture that teaches that God first loved the entire world in the distributive sense. You still insist on interpreting 1Tim 2:3-4 totally out of context! The "all men" in vv. 4 and 6 is
QUALIFIED (i.e. limited) by v. 7, which reads:
1 Tim 2:7
7 And for this purpose I was appointed a herald and an apostle — I am telling the truth, I am not lying —
and a teacher of the true faith to the Gentiles.
NIV
You obviously love your self-imposed ignorance, but here's that newsflash once again: Verse 7 limits "all men" to those Paul was appointed to teach which were Gentiles. But the entire world in the distributive sense consists of Jews and Gentiles. Therefore, the
"all men" in vv. 4 and 6 means all w/o distinction, and not all w/o exception. Paul didn't say in the passage that he was appointed to teach the gospel to Jews and Gentiles.
