Why was sin allowed?
" 'Why' said the artful tempter, 'when God knew what would be the result, did He permit man to be placed on trial, to sin, and bring in misery and death?...There are thousands today echoing the same rebellious complaint against God. They do not see that to deprive man of the freedom of choice would be to rob him of his prerogative as an intelligent being, and make him a mere automation." Patriarchs and Prophets p.331,332 E.G.W.
As I live, saith the Lord GOD, I have no pleasure in the death of the wicked;
but that the wicked turn from his way and live: turn ye, turn ye from your evil
ways; for why will ye die,..
Ezekiel 33:11
