On the issue of God decreeing everything; including all evil

"God decrees that it shall be sinful for the sake of the good that he causes to arise from the sinfulness thereof, whereas man decrees it for the sake of the evil that is in it." ~Jonathan Edwards

God did not decree evil in the sense that he delights in evil as evil. Rather he wills that evil come to pass that good may come of it.

"God is more glorious for having conceived and created and governed a world like this with all its evil. The effort to absolve him by denying his foreknowledge of sin or by denying his control of sin is fatal, and a great dishonor to his word and his wisdom." ~John Piper

The mere fact that God created the tree of knowledge of good and evil shows clear intent purpose and a plan for evil on His part. If God created the possibility of evil and never decreed it to happen and decreed its outcome, the whole universe would spin out of His control into total diabolic chaos. It would mean there are things in the universe who are beyond God's control and comes from another divine source, which God has no control over. The creation of the possibility of evil shows that God decreed evil to happen, but that He ordained both the event and the good outcome of it. We see this in the foreordaining of the death of Jesus before the world was created. Why would God foreordain Jesus to die as the Lamb slain before the foundations of the world if He did not create and decree the definite possibility of sin? It would have been impossible for Satan and man to sin if God, who created everything from nothing, did not create them and the environment they would exist in with the definite possibility to sin. The fact that God foreordained Jesus to die before He created anything shows that He decreed sin and it would happen, but He also planned the good outcome. If we do not say this, it means there was a possibility that sin would never happen. The question then arises; was there a possibility that Satan would not fell, that man would not sin and that Jesus would never die? The answer is no; Satan would fell, man would sin and Jesus would die. Can you see why we have to conclude in that ultimate sense that God did decree sin to happen and also did decree the outcome? The outcome of sin shows that God is not the author of any evil, but is good all the time. No evil can be attributed to Him as His intentions in everything is good and for His glory alone. It is quite a glorious Being who are able to ordain sin to happen without being the author thereof and even work it out to be better than the initial sinful event.
