Paul prays that the Ephesians would grow in their knowledge and understanding of God through the Spirit's wisdom and revelation. He asks God to enlighten their hearts so they comprehend the hope of their calling, the riches of God's inheritance in the saints, and His immense power available to believers. Christ has been exalted above all rule and authority and been appointed head of the church, which is His body through which He fills all things. Paul wants the Ephesians to understand better all that God has given them in Christ so they can live in the fullness and power of their blessings.
