The Scriptures indicate that the following acts of Christ were performed only one time.  Why?  Because the Father was satisfied with the Son’s work.  It was perfect and complete.  We can add nothing to it. This is the New Covenant.

By so much was Jesus made a surety of a better testament.  And they truly were many priests, because they were not suffered to continue by reason of death: But this man, because he continueth ever (lives forever), hath an unchangeable priesthood.  Wherefore he is able also to save them to the uttermost that come unto God by him, seeing he ever liveth to make intercession for them.

For such an high priest became us, who is holy, harmless, undefiled, separate from sinners, and made higher than the heavens; Who needeth not daily, as those high priests, to offer up sacrifice, first for his own sins, and then for the people’s: for this he did once, when he offered up himself.

For the law maketh men high priests which have infirmity; but the word of the oath, which was since the law, maketh the Son, who is consecrated for evermore.  Hebrews 7:21 – 27

But Christ being come an high priest of good things to come, by a greater and more perfect tabernacle, not made with hands, that is to say, not of this building; Neither by the blood of goats and calves, but by his own blood he entered in once into the holy place, having obtained eternal redemption for us.  Hebrews 9:11 & 12

For Christ is not entered into the holy places made with hands, which are the figures of the true; but into heaven itself, now to appear in the presence of God for us:

Nor yet that he should offer himself often, as the high priest entereth into the holy place every year with blood of others; For then must he often have suffered since the foundation of the world: but now once in the end of the world hath he appeared to put away sin by the sacrifice of himself.

And as it is appointed unto men once to die, but after this the judgment: So Christ was once offered to bear the sins of many; and unto them that look for him shall he appear the second time without sin unto salvation.  Hebrews 9:24 – 28

By the which will we are sanctified through the offering of the body of Jesus Christ once for all.  And every priest standeth daily ministering and offering oftentimes the same sacrifices, which can never take away sins: But this man, after he had offered one sacrifice for sins for ever, sat down on the right hand of God; From henceforth expecting till his enemies be made his footstool.  For by one offering he hath perfected for ever them that are sanctified.  Hebrews 10:10 – 14

For Christ also hath once suffered for sins, the just for the unjust, that he might bring us to God, being put to death in the flesh, but quickened (made alive) by the Spirit:  I Peter 3:18

Are you still living under the Old Covenant?
