What are God's attributes?
God is sovereign, holy, righteous, omnipotent, and full of all knowledge. He never goes against His own principles. Because He knows all things, He knows what must be done to reconcile fallen mankind back to Himself through the finished work of the cross.
Les explains that God is sovereign and could act however He wanted, yet He never goes against His own principles. In the context of Romans 8:32, Les highlights that God is holy, righteous, omnipotent, and full of all knowledge. Because He possesses complete knowledge, He knows what has to be done to reconcile fallen man back to Himself. That reconciliation is based on the finished work of the cross, where God did not spare His Son but did so to purchase mankind back to Himself.
