God has a clear foreknowledge of predestination in eternity past, then the calling, justifying, and glorifying occurs in that sequence.
Romans 8:29For those God foreknew, He also predestined to be conformed to the image of His Son, so that He would be the firstborn among many brothers. 30And those He predestined, He also called; those He called, He also justified; those He justified, He also glorified.
Actually, in the mind of God, they have already taken place. This is why, the Spirit led Paul to use these Aorist, Active verbs in the Greek. They are all past tense. Also, the action in these verbs are all God. God is making them happen. So you could interpret them this way:
God Foreknew, in an intimate fashion, then He predestinated them, then He called them, Then He justified them, Then He glorified them, on the surety of His Sovereignty and Eternal existence.
