For truly I say to you, Until heaven and earth pass away, one iota or one serif shall by no means pass away from the law until all come to pass.
The fulfillment of the law will last until the end of the millennium, at which time the heavens and the earth will pass away. Before that takes place, not one iota or tittle of the old law will be annulled. However, what is covered by the prophets goes farther than the millennium, reaching into the new heaven and the new earth.
Christ fulfilled the law in three ways. He Himself kept the law. However, because we did not keep it, He died on the cross for our transgressions of the law. His substitutionary death brought in the resurrection life, which has been imparted into our being. By His resurrection life we are able to fulfill the requirements of the new, higher law. By these three steps Christ has more than fulfilled the old law. He kept it, He died for us, and His death brought into us the resurrection life to strengthen us for fulfilling the requirements of the new law. Today we are not trying to keep the lower law; rather, we are keeping the uplifted, higher law through the highest life that is in us. Now we are able to keep the highest law.
