Which Covenant?

The Bible tells us Jesus shed his blood to seal the new covenant (Matthew 26:28) which is the final covenant with mankind. It was not the blood of animals, but the blood of Jesus that sealed this final covenant. The first covenant was dedicated with the blood of animals (Exodus 24:8; Hebrews 9:18-20) but the new covenant under which we live today is the final covenant. This is not an extension of the old covenant but it is something new. The Bible says then old covenant was only temporary and was to last till Jesus came (Romans 7:7-25). Jesus taught that the old covenant was in force till it was fulfilled. When was that done? At the cross. (Matthew 5:17-18; Colossians 2:8-14) This new covenant tells us how to come to God. It is not through Moses or by keeping the law. It is through Christ and obeying the gospel The new covenant provides for pardon on the merits of Christ’s blood and is given to all who obey Him (Hebrews 5:8-9). Why would anyone want to go back to an inferior and outmoded system that offers so little in comparison to receiving so much under the new covenant?
