What does Ephesians 1:8 mean?

The grace God has given us is explained as something poured on in generous amounts. God did not give us the bare minimum amount of grace needed to have access to God. Instead, He piled it abundantly on us. We have more than enough (Ephesians 3:20). In 1 Corinthians 2:9 Paul says, "As it is written, 'What no eye has seen, nor ear heard, nor the heart of man imagined, what God has prepared for those who love him.'"

This grace was given abundantly, yet also was not wasted. God is always thoughtful in the way He blesses us. He knows what is best and provides accordingly. Paul also notes in this letter that God gives a Spirit of wisdom (Ephesians 1:17) and that He desires the wisdom of God to be known in the heavenly places (Ephesians 3:10). Insight also comes up again in this letter in 3:4 where Paul speaks of perceiving his insight into the mystery of Christ.
