The book of Ephesians sets forth many of the doctrines of the Christian Faith. It is filled with comforting passages like this prayer for the church, the Body of Christ:
“I keep asking that the God of our Lord Jesus Christ, the
glorious Father, may give you the Spirit of wisdom and revelation, so that you may know him better. I pray that the eyes of your heart may be enlightened in order that you
may know the hope to which he has called you, the riches of his glorious
inheritance in his holy people, and his incomparably great power for us who believe. That
power is the same as the mighty strength he exerted when he raised Christ from the dead and seated him
at his right hand in the heavenly realms, far above all rule and authority, power and dominion, and
every name that is invoked, not only in the present age but also in the one to
come. And God placed all things under his feet and appointed him to be head
over everything for the church, which is his body, the fullness of him who fills everything
in every way.”
(Ephesians 1:17-23 NIV) [1]
