'Remember' in the Bible

Therefore, remember that at one time you Gentiles by birth, who are called “Uncircumcision” by those who called themselves “Circumcision,” [itself a mere mark] which is made in the flesh by human hands—

remember that at that time you were separated from Christ [excluded from any relationship with Him], alienated from the commonwealth of Israel, and strangers to the covenants of promise [with no share in the sacred Messianic promise and without knowledge of God’s agreements], having no hope [in His promise] and [living] in the world without God.
