Ephesians 1:3–14 praises God for the blessings He has provided. Paul ties together the ideas of predestination, God’s glory, the salvation of His people, and the rights we have as children of God. In particular, believers are blessed because God chose, before creation, to save us. That salvation came at a great cost: the death of Jesus Christ. As children of God, we can be confident that God will give us what He has promised: namely, an eternity with Him in heaven.
