God is the first and last eternal Person with autonomous will, which is His spiritual image. But when creating spiritual beings in His image, He is no longer the only person with autonomous will.God is the only Person whose will is autonomous.
False teachings always descend into argumentative folly, such as God's eternal image must be separated and exclusive of His autonomous will, so that man created in His image does not also have His autonomous will.
Natural beasts have no free will autonomous from nature. They do only what nature and God's wills them to do, without freedom of choice to do otherwise. Man having no free autonomous will is the natural man's rejection of the spiritual man created in God's image.
Angels also have autonomous will, and is the first creation of God to independently lift up his will against God.
Isa 14:12How art thou fallen from heaven, O Lucifer, son of the morning! how art thou cut down to the ground, which didst weaken the nations! For thou hast said in thine heart, I will ascend into heaven, I will exalt my throne above the stars of God: I will sit also upon the mount of the congregation, in the sides of the north: I will ascend above the heights of the clouds; I will be like the most High.
Autonomous will is proven by independently rebelling against God. Spiritual autonomy of will is the power to choose indepently of God, whether angel or man.
Gen 3:4And the serpent said unto the woman, Ye shall not surely die: {3:5} For God doth know that in the day ye eat thereof, then your eyes shall be opened, and ye shall be as gods, knowing good and evil.
However, autonomy of will is not autonomy of judgment. The eternal power of the free will is not eternally free from God's law of judgment.
Angels and men can act like gods independent of God's will, but they cannot abide forever like gods without His judgment.
Heb{9:27} And as it is appointed unto men once to die, but after this the judgment:
Autonomy of will continues after the judgment, but willing independence from God becomes forever autonomously apart from the light and felloswhip of God and the Lamb dwelling among men.
Jde 1:12These are spots in your feasts of charity, when they feast with you, feeding themselves without fear: clouds they are without water, carried about of winds; trees whose fruit withereth, without fruit, twice dead, plucked up by the roots; Raging waves of the sea, foaming out their own shame; wandering stars, to whom is reserved the blackness of darkness for ever.
2 Tim 1:7Who shall be punished with everlasting destruction from the presence of the Lord, and from the glory of his power;
