His Death alone Sanctified those He died for !
We know that Christ could not have died for all men without exception, because all for whom He died, gave Himself for, He once and for all sanctified them.
Heb 10:9-10
9 Then said he, Lo, I come to do thy will, O God. He taketh away the first, that he may establish the second.
10 By the which will we are sanctified through the offering of the body of Jesus Christ once for all.
All those Christ died for [ the offering of His body] He sanctified them by His death or His offering of Himself. Now if this be True, those whom are born sinners by nature., but yet Christ died for them, then legally they are sanctified once and for all. The word sanctified in the greek is the word hagiazo and means:
to render or acknowledge, or to be venerable or hallow
to separate from profane things and dedicate to God
consecrate things to God
dedicate people to God
to purify
to cleanse externally
to purify by expiation: free from the guilt of sin
to purify internally by renewing of the soul
Also it is in the Perfect Tense which means:
The perfect tense in Greek corresponds to the perfect tense in English, and describes an action which is viewed as having been completed in the past, once and for all, not needing to be repeated.
So by one offering [His Death] in the past, those Christ died for have been permanently consecrated to God, freed from the guilt of sin.
Now can one be sanctified before they are born ? If one was sanctified by Christ death 2000 yrs ago, and they are born in 1945 as a sinner, can they still be sanctified by the Death of Christ ? Yes they can be sanctified before they are born, and yes they are sanctified while being born a sinner by nature. Case and example is Jeremiah Lets look at Jer 1:5
5 Before I formed thee in the belly I knew thee; and before thou camest forth out of the womb I sanctified thee, and I ordained thee a prophet unto the nations.
Jeremiah's being sanctified [by the offering of Christ] by God before he came forth out of the womb, and being appointed a prophet, did by no means exempt him from being born a sinner by nature, for all men are born sinners [Rom 5:12] yes even Jeremiah, but nevertheless He was in the Purpose of God already sanctified, set apart for a Purpose, and legally free from guilt. Was Jeremiah born a sinner and a enemy of God by Nature ? Yes, but was he born legally condemned by God for his sins ? No, legally he was not guilty and set apart for the Holy Purpose of God, as all men and women are for whom Christ died Rev 5:9-10
9 And they sung a new song, saying, Thou art worthy to take the book, and to open the seals thereof: for thou wast slain, and hast redeemed us to God by thy blood out of every kindred, and tongue, and people, and nation;
10 And hast made us unto our God kings and priests: and we shall reign on the earth.
For being appointed a OT Prophet to God as Jeremiah is no more important to God as being appointed or made into a Kingdom of Priest unto God, both were for His own Glory and Praise !347
So Christ could not have died for all the world without exception, because all without exception are not sanctified.
