Did Christ die for every person according to Les's teaching?
Yes. Scripture is said to affirm that Christ died for every man and tasted death for every man, and that God is not willing that any should perish. This stands alongside the teaching that believers were chosen in Him before the foundation of the world.
Les teaches that Scripture is full of the truth that Christ died for every man and tasted death for every man, and that God is not willing that any should perish. Yet he also points to Scripture saying believers were chosen before the foundation of the world. He says he cannot explain those two facts but lets them stand in Scripture by faith, trusting God to settle the controversy. His illustration is the river of humanity with doors of opportunity marked 'Whosoever will may come'; after passing through, one looks back and sees 'Chosen in Him' before the world was created. He concludes that we must decide for ourselves, and the moment we decide, God says, 'I chose you.'
