Ref: Mark 14:24, Jeremiah 32:40
What then are the terms of the covenant that he infallibly secured by his blood? The prophet Jeremiah describes some of them: “I will make a new covenant . . . this is the covenant that I will make . . . I will put my law within them, and I will write it on their hearts. . . . For I will forgive their iniquity, and I will remember their sin no more” (Jeremiah 31:31-34). The suffering and death of Christ guarantees the inner change of his people (the law written on their hearts) and the forgiveness of their sins.
And the miracle is not only the creation of our faith, but the securing of our faithfulness. “I will make with them an everlasting covenant. . . . I will put the fear of me in their hearts, that they may not turn from me” (Jeremiah 32:40). When Christ died, he secured for his people not only new hearts but new security. He will not let them turn from him. He will keep them. They will persevere. The blood of the covenant guarantees it.
After reading today’s chapter, I was struck (again) by just how small our contribution to our salvation is. We didn’t initiate it (God had it planned before the ages began). We didn’t implement it (Christ gave his life). We don’t guarantee its outcome (God has that taken care of).
How humbling. How God–exalting.
