Time is the very process by which God’s plan unfolds and rolls out. God created angels, then time, and then man to resolve the Angelic Revolution Conflict, and to restore eternity, in time, through Jesus Christ.
The consummation of time will occur when all creation is restored to its original status-purpose by God and to the praise and glory of God.
“That which God ordained in eternity is undaunted in time! Time may be titled ‘The Restoration.'” – C. S. Craig
God exists outside of time; He created time, and will end time when every aspect of His plan is complete, and we will exist in eternity, with Him, never to depart.
