The Perfect will of God is that everyone does His will. The Permissive Will of God is that He permits men, such as Adam and Eve, to do their own will, even if it was to reject Him, and experience God's wrath and judgment, such as in the Garden of Eden.
God's Perfect Will is that Israel be gathered together like a hen gathers its chicks. But God's Permissive Will was to allow them to reject Him.
Jesus stated: "Jerusalem, Jerusalem, who kills the prophets and stones those who are sent to her! How often I wanted to gather your children together, the way a hen gathers her chicks under her wings, and you were unwilling." (Matthew 23:27)
What could be a better statement of God's Perfect Will and His Permissive Will?
