2 Corinthians 5:10 (NIV) For we must all appear before the judgment seat of Christ, that each one may receive what is due him for the things done while in the body, whether good or bad.
A person may cause evil to others not only by his actions but by his inaction, and in either case he is justly accountable to them for the injury. -- John Stuart Mill (1806-1873)
