Then what advantage has the Jew? Or what is the value of circumcision? 2 Much in every way. To begin with, the Jews were entrusted with the oracles of God. 3 What if some were unfaithful? Does their faithlessness nullify the faithfulness of God? 4 By no means! Let God be true though every one were a liar, as it is written, “That you may be justified in your words, and prevail when you are judged.”
Your unfaithfulness does not determine the faithfulness of God. That may seem strange to you, but grace would not be grace if it was dependent upon our ability to earn it.
The Jews had a great advantage over the other nations in that God had given them specific promises concerning the means of their salvation. Through their forefather Abraham God had promised to bless them and make them a blessing and he sealed his promise with the sign of circumcision. In this agreement, or covenant, the fulfilment of the promise was all on God. He was the one who took all the responsibility. All the Jews had to do was believe and trust that God would make his promise good.
When we look at their story we find that they failed to trust God and instead turned to other gods or attempted to appease God by the works of sacrifices absent of faith. This unfaithfulness to the promise brought to them judgment, but their unfaithfulness did not nullify or negate the promise because God was still faithful to his word. We know that because time and time again God said that he had preserved for himself a remnant, those who believed, who trusted his word and believed in the promise.
Our salvation is based in the very same promise, in the promise given to Abraham. That promise has been fulfilled in Christ who brings the blessing of free grace not only to the Jews, but also to the Gentiles, to you and me. Since our salvation is wrapped up in the promise of God and what he said he will do for us that means that our sins, or acts of unfaithfulness, cannot negate the promise of God to save us. We will falter and fail and fall. We will sin against a holy and righteous God, but as Jeremiah writes in Lamentations, God’s mercies are new every morning.
My friends, your salvation does not depend on you. It is found only in the one who can save; the one who is always faithful, the one who lived a perfect life for you. Look to Christ the faithful one.
