The gospel of God's Son is Good News, the blessed expression of His person and work. All, until the gospel, was a holy God's claim upon sinful man. The gospel does not alter this claim but maintains it. It shows that all is hopeless for fallen man, for he can never meet that righteous claim. But the gospel brings in the power of God—power on behalf of man.
It is not power to help man meet the claims of God upon him; it reveals the righteousness of God consequent upon man being altogether without strength. Thus peace flows into the soul that ceases from everything else and submits to the revealed righteousness of God, which is given to everyone that believes in Him. If I am in the presence of God, help will not do. I am lost.
I need righteousness and pardon; and, to stand before God, I need them now. The soul cannot have solid peace until, in the presence of God, by His power, it has His righteousness and pardon.
The Apostle Paul says, "I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to every one that believeth... for therein is the righteousness of God revealed." This righteousness is declared unto all, to Jew and Gentile, yea, to every creature, and it is upon all them that believe.
