Here are examples of how the Lord Jesus has completed the Covenant and the part that we also take in the process:
1) Exchanging of coats or robes
We come to this covenant clothed in sin and unrighteousness. He comes clothed in holiness and righteousness. We put on His righteousness.
“For He hath made Him to be sin for us, who knew no sin; that we might be made the righteousness of God in Him.” – Second Corinthians 5:21
“I will greatly rejoice in the LORD, my soul shall be joyful in my God; for he hath clothed me with the garments of salvation, he hath covered me with the robe of righteousness…” – Isaiah 61:10He takes our sins upon Him and we take His holiness for ours. What an exchange!
2) Removing and exchanging (weapons) belts
“Wherefore take unto you the whole armor of God … and having on the breastplate of righteousness … taking the shield of faith … take the helmet of salvation … and the sword of the Spirit, which is the word of God.” – Ephesians 6:13-173) Cutting the covenant
“This is the covenant that I will make with them after those days, saith the Lord, I will put my laws into their hearts, and in their minds will I write them; And their sins and iniquities will I remember no more.” – Hebrews 10:16-17
“… and the blood of Jesus Christ his Son cleanseth us from all sin. – First John 1:74) Cutting of hands and intermingling of blood
Jesus was both man and God. He was holy and also human. As we have the shed blood of Jesus Christ applied to our hearts, His blood cleanses us from all sin and we are also made holy. Our lives are forever intermingled with His.
“… Unto him that loved us, and washed us from our sins in his own blood,” – Revelation 1:55) Exchanging of names by incorporating part of their name
Jesus took on the name, "Son of Man" and we take on the name Christian. We are forever in the family of God.
“… And the disciples were called Christians first in Antioch.” – Acts 11:266) Make a scar
Jesus has the scars of the nails in His hands and the feet and the spear in His side. We have the circumcision of the heart.
“But he is a Jew, which is one inwardly; and circumcision is that of the heart, in the spirit, and not in the letter; whose praise is not of men, but of God.” – Romans 2:297) The covenant terms are exchanged
The entire Bible gives us the Covenant.
“Thy word have I hid in mine heart, that I might not sin against thee.” – Psalm 119:118) Eat a memorial meal
“And when He had given thanks, He broke it, and said, Take, eat: this is my body, which is broken for you: this do in remembrance of Me. After the same manner also He took the cup, when He had supped, saying, This cup is the new testament in My blood: this do ye, as oft as ye drink it, in remembrance of Me.” – First Corinthians 11: 24-259) A tree is planted and sprinkled with the blood of the sacrifice
The cross that Jesus died on was the tree that the blood of the sacrifice was sprinkled on and it still is a memorial of His covenant with us to this day.
“And, having made peace through the blood of his cross, by him to reconcile all things unto himself;” – Colossians 1:20The Blood Covenant has been in existence from the Beginning. It is found in both the Old Testament and the New Testament. Praise the Lord for His wonderful plan! Praise Him for including us, sinners, in His plan. Praise the Lord for the atoning blood of the Lord Jesus!
