God predestined us BECAUSE He knew we would be saved.
Not, to save us.
If God wanted Moses to become the Bride of Christ?
God would have predestined for Moses to be alive during the Church age, so when he believed?
Moses would be a member of the body of Christ.
You're getting it straight, sir.
But you are not! God predestined those He [fore]KNEW in eternity. Plus God's will is not contingent on any of his creatures' wills.
Here's another newsflash for you: All the OT saints are the Bride of Christ along with the NT saints. God was always the Husband to the remnant of believing Israel. God doesn't have multiple peoples, that he saves with multiple gospels for multiple eschatological reasons.
