Your quote from Piper says God is the author of sin. I was only quoting him.
Also, I watched the film clip you posted in the other thread and there Piper says all sins and evil were preordained by God, all wife beatings ... I do not remember the whole list. But it certainly sounded as if he attributes all sin to God in that God preordained the evil.
As I said in other posts, what kind of father would predestine pain and suffering on his children in order to show how loving he is?
You say they have a choice, but at the same time you say they were predestined to select wrongly .. so they really had no choice. That can only be the logical conclusion of predestination and/or pre-ordination.
I can only go by what you quote from him.
No sir. What you did was make the leap from Piper saying that God ordained that sin be to "men do not choose to sin".
Just because God ordained something to coem to pass does not mean that men do not choose freely to do that thing that God ordained to come to pass.
God does not compel men to sin.
He in his divine brilliance has ordered a world in which sin will most certainly exist. He has done this that he might display and bestow the full measure of his love upon his people.
Without sin there can be no saving grace to be praised and to be experienced forever.
Without sin there can be no infinite mercy to be glorified and appreciated forever.
Without sin there can be no redemption from sin and no Redeemer to receive honor and glory for it forever; and there can be no redeemed people to bask in the wonder of God's redeeming love forever.
Why would you want God NOT to want these things???
