Jesus said, “For truly, I say to you, until heaven and earth pass away, not an iota, not a dot, will pass from the Law until all is accomplished.”
But then multitudinous iotas and dots began to pass. Circumcision for example. So Paul wrote to the Galatians: “For in Christ Jesus neither circumcision nor uncircumcision counts for anything, but only faith working through love.” But he had told the Galatians and others that love was the fulfillment of the Law. And the Law commanded circumcision. So how could one say that one could fulfill the Law and yet circumcision was no longer commanded?
Answer: new heavens and earth: “For neither circumcision counts for anything, nor uncircumcision, but a new creation” (Galatians 6.15).
