Yes He has. Jesus introduced a new covenant. Check the NT. It occurred at the cross. Only those who enter into that covenant by faith will make it. I highlight recommend you embrace it.
When Jesus instituted the Lord’s supper in Matthew 26:28, which represented His shed blood for the remission of our sins, He declared: “this is my blood of the new testament [diathēkē], which is shed for many for the remission of sins.”
Jesus was speaking here about His death! The Greek word here “testament” is diathēkē meaning covenant or testament. The shedding of His blood, which expressly secured “the remission of sins” for His elect, constituted “the new covenant.”
diathēkē is a disposition, that is, (specifically) a contract (especially a devisory will): - covenant, testament. A testament is exactly the same as a covenant. It is the exact same word and meaning. Basically, the terms "covenant" and "testament" are interchangeable and synonymous. They are translations of the same Greek word.
The covenant is a testament, a will. A will cannot come into force unless the covenant maker dies first.
Mark 14:24 parallels: “he said unto them, This is my blood of the new testament, which is shed for many.”
Luke 22:19-20 agrees: “And he took bread, and gave thanks, and brake it, and gave unto them, saying, This is my body which is given for you: this do in remembrance of me. Likewise also the cup after supper, saying, This cup is the new testament in my blood, which is shed for you.”
Some seem content to partake in what they deny.
1 Corinthians 11:24-26: “And when he had given thanks, he brake 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 [diathēkē or covenant] in my blood: this do ye, as oft as ye drink it, in remembrance of me. For as often as ye eat this bread, and drink this cup, ye do shew the Lord's death till he come.”
Believers are asked to remember the Lord's death – which is “the new testament [diathēkē or covenant] in [His] blood” – until He returns. “The new covenant” is here identified with “the Lord's death.” There is no way around it.
