That at that time ye were without Christ, being aliens from the commonwealth of Israel, and strangers from the covenants of promise, having no hope, and without God in the world: That at that time ye were without Christ - Not only were not Christians, but had no knowledge of the Christ or Messiah, and no title to the blessings which were to proceed from him.
Aliens from the commonwealth of Israel - Ye were by your birth, idolatry, etc., alienated from the commonwealth of Israel - from the civil and religious privileges of the Jewish people.
Strangers from the covenants of promise - Having no part in the promise of the covenant made with Abraham, whether considered as relating to his natural or spiritual seed; and no part in that of the covenant made at Horeb with the Israelites, when a holy law was given them, and God condescended to dwell among them, and to lead them to the promised land.
Having no hope - Either of the pardon of sin or of the resurrection of the body, nor indeed of the immortality of the soul. Of all these things the Gentiles had no rational or well-grounded hope.
Without God in the world - They had gods many, and lords many; but in no Gentile nation was the true God known: nor indeed had they any correct notion of the Divine nature. Their idols were by nature no gods - they could neither do evil nor good, and therefore they were properly without God, having no true object of worship, and no source of comfort. He who has neither God nor Christ is in a most deplorable state; he has neither a God to worship, nor a Christ to justify him. And this is the state of every man who is living without the grace and Spirit of Christ. All such, whatever they may profess, are no better than practical atheists.
