We disagree, and unless you can biblically prove what you stated, we will continue to disagree.
David committed adultery that was outside the perfect will of God as the act of adultery is a sin; yet, it was within the permissive will of God to allow the act of adultery to happen.
Eve ate from the forbidden tree. That was outside the perfect will of God, an act of disobedience to His command; yet, by His permissive will, God allowed sin to enter the world.
Sin is never within the perfect will of God, but remains within the permissive will of God every time.
As I said, we disagree.
