"Blessed be the God and Father of our Lord Jesus Christ, who has blessed us in Christ with every spiritual blessing in the heavenly places, even as he chose us in him before the foundation of the world, that we should be holy and blameless before him. He destined us before him in love to be his sons through Jesus Christ, according to the purpose of his will, to the praise of his glorious grace which he freely bestowed on us in the Beloved."
