Jesus Was. Jesus Is. Jesus Did.
Romans 8:3 - For God has done what the law (You must), weakened by the flesh, could not do (You can’t). By sending his own Son in the likeness of sinful flesh and for sin, he condemned sin in the flesh (Jesus did).
What you are required to do and what you can’t do - Christ did.
Jesus met the standard on our behalf. He climbed the unclimbable heights for us. He was “tempted in every way, just as we are—yet he did not sin” (Heb. 4:15). He lived a life of perfect obedience to the Father both passively and actively.
Now, if you are in Christ you are “perfect as our heavenly father is perfect.” The very righteousness of Christ has been imputed to you.
The good news is not that the law is relaxed by Jesus in the New Testament - the good news is that the law is perfectly fulfilled by Him. This is the Christian message. This is the gospel.
So come to him all you who are weary, tired, and burned out, and he will give you rest. Embrace the freedom that Christ is offering. Bathe in his intoxicating grace. Dwell on what he has done for you. Feast at the table he has prepared for you. Let that heavy yoke of trying to earn his favor fall from your shoulders. In Christ, you have his favor. In Christ, you are right with God. In Christ, you are blessed beyond measure.
So rest. Rest in that he did what we could not do for ourselves. He lived the life we could not live and died the death that we should have died. He was perfect. Now, through faith in Christ alone, that perfection is ours.
I have no better words for you than these: You Must. You Can't. Jesus Did.
The question is, can you let grace have the final word, or will you add a "but"? I know it's not natural and feels too good to be true, but let Christ's work be enough. Let grace win the day in your life. You Must. You Can't. Jesus Did - no "but" is required.
