"When Jesus had taken vinegar, he said : It is accomplished. Then, having lowered his head, he put his spirit back." John 19: 30
On the cross, after taking the vinegar, Jesus said : "It's accomplished" (this word is the equivalent of "ACQUITTY" written on a regulated invoice). The work of redemption for which Jesus came into the world is completely finished.
God shows that he accepts the sacrifice of his Son by raising him from the dead, raising him in glory, making him sit on his right hand in heaven: these facts indicate that the work of Christ is accomplished Once and for all and that its consequences are final.
God now sees us in Christ, holy, justified, glorified (Romans 8: 30). "We have been sanctified by the offering of the body of Jesus Christ made once and for all ... By one offering he has perpetually perfected those who are sanctified" (Heb 10: 10-14). Christ, the perfect victim, has accomplished a perfect work: everything, in the offering that Christ made of himself, was to glory and for the satisfaction of God.
If Jesus had not uttered this saying on the cross : "It's accomplished," no one today would be freed from the slavery of sin ; No one would be assured of his present and eternal salvation ; No one would know peace with God and would have true joy in his heart; No one would be sure of one day contemplating the glory of God. There would be no one to know the grace of God and his undeserved love, no one in whom God could pour his love through the Holy Spirit.
There would be no children of God, no family of God on earth, no possibility of communion with the Father and his Son Jesus Christ, nor communion among believers.
If Jesus had not uttered the cry of his great victory on the cross, no one could praise the God and Father of our Lord Jesus Christ, nor exalt the Lord for the perfection of his work !
Then, gathered today with those whom God has redeemed, give glory and power "to him who loves us, and has washed us from our sins in his blood - and made us a kingdom, priests for his God And Father" (Rev. 1. 5, 6).
