While reflecting on what stands at the heart of the gospel, I thought first of what Paul called, “the goal of the commandment” in Titus 1:5. “Now the end (goal) of the commandment is love from a pure heart, from a good conscience, and from sincere faith.”
That is indeed the outworking of the fruit of His life within us, as to our sanctification, but it’s foundation and root is deeper still. It’s root is the resurrection life of Jesus, as both imputed and imparted to the justified believer. Its source is as far from the strength of nature as the budding of Aaron’s rod.
Paul says this righteousness is now revealed in the recently unveiled “mystery of the gospel” (Eph 6:19).
“For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to every one that believeth; to the Jew first, and also to the Greek. For therein is the righteousness of God revealed from faith to faith: as it is written, The just shall live by faith” (Ro 1:7).
Paul shows that the mystery that could not come to full light until the revelation of the gospel was fully foretold in the prophetic writings (Acts 26:22-23). Yet, kept secret in times past till the appointed time of revelation (1Cor 2:7-8; Ro 16:25-26). Why only now, with the post-resurrection revelation of the gospel, is this righteousness revealed? Wasn’t the righteousness of God already fully revealed and well established all throughout the scriptures? What kind of righteousness is this that has waited till now to be “revealed”?
