So are you saying that free will creates evil, therefore we can create something God can't?
Yes and No.
Evil is when '
free-will' choses to go contrary to God's will. Even Jesus said, 'not my will, but thine be done.'
If free-will is not free, then it is not
free-will. To only have one choice is not a choice.
"You can have any color of car you like as long as it is black." . . . that is no choice at all.
The extent to which God created evil is only to the extent that He created a system that requires 'goodness' in order to be the only path to the 'good of the whole
.
' God has already chosen to follow that path. Now, we get to chose whether to follow Him in that path, or not.
God did create the power to destroy and punish that which is contrary to His will. That force (our God is a consuming fire) may be destructive, at times, but is a necessary force and final trump card when dealing with other free-wills. That force may be destructive, but not evil.
God's sovereignty is that He allows free-will but retains the final judgment. His purpose is to find and develop those of free-will who will submit to His purpose and His way, just as a husband seeks a wife who will do the same.
God could choose (He does have free-will) to do or become evil; however, that would bring destruction to the creation and even to Himself. God remains God, not just because He has ultimate power but also because He is committed to the right use of that power. Any power misused can bring destruction. God's power is not immune to the possibility of misuse. God has demonstrated, and we have faith, that His goodness prevails and that the fate of the universe has an expected good outcome. This ultimately hinged upon the success of Jesus! If Jesus had failed, God could have destroyed the whole of the universe and none would be the wiser.
ALL THINGS WERE CREATED FOR THE PURPOSE OF THE MANIFESTATION OF THE SON OF GOD (JESUS)
God's desire that sparked the creation was to have a begotten Son... a Son who would be obedient, and faithful, and who could share His (God's) throne, and Glory, and complete mind. All others share a part. Only Jesus is the fulness of the Godhead bodily. Only Jesus has access to the full measure of the Glory and mind of God.
When the final Great White Throne Judgment is over there will be a remnant that will have a Godly seed and the universe will ultimately be filled with those of free-will who will have learned the lesson that God is good, and just, and the only one who can be trusted with the sustaining of the universe. Adam's sin contaminated his seed, and by extension, all those born of him. During the thousand-year reign, God will be purging the sin nature. The final battle, when fire descends, will effectively eradicate the remaining Ungodly Seed... ie., those holding on to the sin nature.
God is letting sin run its course so future generations will never be able to say, "If sin had only been tried our way, it would have worked."... because all the ways would have been tried, and the end of all sin is destruction.
