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. In love he predestined us for adoption as sons through Jesus Christ, according to the purpose of his will Ephesians 1:3–5, ESV
For what reason did the God and Father of our Lord Jesus Christ chose (elect) all in Christ before the foundation of world? It was that they would be holy (ἁγίους) and blameless (ἀμώμους) before him. The Puritans have always been accused of being legalistic and way too concerned about Christians living holy and blameless lives.
I heard a Jeopardy clue not long ago that actually defined this aspect of them as being “harsh” and “stern.” Is it an unreasonable thing to command that believers conform their lives unto holy living and be separate from the world and its ways?
