“For by one offering he hath perfected for ever them that are sanctified.”
King James Version (KJV)
10:14 He hath perfected them for ever - That is, has done all that was needful in order to their full reconciliation with God.
Heb 10:14 For by one offering, that of the cross, he hath perfected for ever. Given them perfect consciences free from a sense of the guilt of sin. Them that are sanctified. All Christ's brethren are sanctified (Heb 2:11); so are all whose sins are forgiven (Heb 10:10,29); all saints are sanctified (1Co 1:2); hence all Christians are called the "sanctified".
