Becoming a Christian involves a change in attitudes and life empowered by the Holy Spirit. It is necessary to put off the past life in order to put on the new life.

Paul introduces the reality of spiritual warfare that every Christian faces together with the resources that God provides to fight against the enemy. Roman soldiers are guarding him and he uses their armour to explain these resources.

Paul prays that the Ephesians will know how wide, how long, how high and how deep God’s love is so that they can be strengthened in their faith and understanding of God.
