Romans 5:7-8

(7-8) What makes the sacrifice of Christ so paradoxical is that it was undergone for sinners. Even for a righteous man it is rare enough to find another who will be ready to lay down his life. Yet some such persons there are. The one thing which is most extraordinary in the death of Christ, and which most tends to throw into relief the love of God as displayed in it, is that He died for men as sinners, and at the very moment when they were sinning all around Him.
