Justification is a legal proclamation. It is not a decision held for the lifetime of the accused then applied if the accused earns the right to the proclamation. Jesus has been sacrificed ONCE FOR ALL FOREVER. Jesus told the rulers:
John 6:29 Jesus answered and said unto them, This is the work of God, that ye believe on him whom he hath sent.
When they believe, what happens?
Acts 2:1-4 Now when the day of Pentecost had come, they were all with one accord in one place. Suddenly there came from the sky a sound like the rushing of a mighty wind, and it filled all the house where they were sitting. Tongues like fire appeared and were distributed to them, and one sat on each of them. They were all filled with the Holy Spirit ...
Acts 10:44&45 While Peter was still speaking these words, the Holy Spirit fell on all those who heard the word. They of the circumcision who believed were amazed, as many as came with Peter, because the gift of the Holy Spirit was also poured out on the Gentiles.
Justification happens in the minute one does what Jesus told the leaders they must do as the work God requires. God puts the exclamation point on that immediacy with the coming of the Holy Spirit upon the believer.
At this point perhaps you are asking 'so what is the rest of living according to God's commandments supposed to accomplish if not making one worthy of Justification to be received upon death? ... That is a good question.
The Blood of Christ was not for drinking, it was for spreading upon the Mercy Seat in Heaven, so that the law of sin and death was then annulled for all, that is ALL who are in Christ. Paul says: Romans 8:1 There is therefore now no condemnation to them which are in Christ Jesus, who walk not after the flesh, but after the Spirit.
Perhaps that causes you to ask, so who is walking 'after the spirit'? what does that mean? Another good question.
When we are born from above, that moment when in this life God justifies us because we place our faith in Christ, He adopts us into His family by the coming into us of His Holy Spirit. RomaNS 8:2-6 For the law of the Spirit of life in Christ Jesus hath made me free from the law of sin and death. Verse 3 Strongs Parallel Speaking Sacred N Copy/Paste For what the law could not do, in that it was weak through the flesh, God sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh: That the righteousness of the law might be fulfilled in us, who walk not after the flesh, but after the Spirit. For they that are after the flesh do mind the things of the flesh; but they that are after the Spirit the things of the Spirit. For to be carnally minded is death; but to be spiritually minded is life and peace.
YOU CANNOT BE SPIRITUALLY MINDED IF YOU BELIEVE YOU MUST RE-SACRIFICE JESUS EACH TIME YOU ARE PERSUADTED OF HAVING VIOLATED THE LAW OF SIN AND DEATH. YOU CANNOT BE SPIRITUALLY MINDED IF YOU BELIEVE YOU MUST DRINK THE BLOOD OF CHRIST TO KEEP ABSOLVING YOUR SINS. Paul says there is therefore now, not after each Eucharist only, no condemnation for those who walk after the spirit. How do you walk after the spirit? ... By faith, by faithing in Him as the perfect Atonement for you and believing His blood covers the law of sin and death for you. When you partake of the Eucharist, you do so as an outward exhibition that you are spiritually accepting His Sacrifice, His blood on the law of sin and death, for you. You are not eating His literal flesh or drinking His literal blood. His blood was shed and spread upon the Mercy Seat for you. His blood was so perfect that it does not need to be shed over and over, into your belly, to cover the law of sin and death for you. You partake of the Eucharist IN REMEMBRANCE of His work for you. In faith you walk not after the flesh but after the spirit that is IN YOU by the presence of His Holy Spirit Who comes when you believe, as illustrated by Pentecost and the House of Cornelius.
You seem to be confused about the words of Jesus and His teaching. I hope that you read the whole article.
May God help you understand.
