Psalms 149:4

“For the Lord taketh pleasure in his people, etc.] Not all mankind; though they are all his people by creation, and are under the care of his providence; yet they are not all acceptable to him; some are abhorred by him for their sins and transgressions: but these are a special and peculiar people, whom he has foreknown and chosen, taken into the covenant of his grace, and provided in it blessings for them; whom he has given to Christ, and he has redeemed; and who are called by the Spirit and grace of God, whereby they appear to be his people.
