How We are to Respond to God's Promises
How are we to respond to God's promises of blessing? Such promises are not automatically at work in every life that hears them. Some people respond correctly, while others respond improperly. Some enjoy the benefits of God's promises, whereas others do not. In these two verses, we are given the necessary response to all that pertains to the gospel of grace. That response is faith. This would certainly include living by the promises of God.
Paul was unashamed of the gospel because he knew its effective character. "For I am not ashamed of the gospel of Christ, for it is thepower of God to salvation." The good news about Jesus Christ is essentially the grace of God proclaimed to man: "the ministry which I received from the Lord Jesus, to testify to the gospel of the grace of God" (Acts 20:24). This grace is God's power poured out unto the saving of souls. This power is experienced by all who place their faithin the gospel, whether Jew or Gentile: "for everyone who believes, for the Jew first and also for the Greek." The gospel is effective, because it holds forth God's righteousness to sinful man, if he is willing totrust in the Lord. "For in it the righteousness of God is revealed fromfaith to faith."
The gospel is referred to in the Scriptures as a promise. "And this is the promise that He has promised us—eternal life" (1 John 2:25). The gospel is often stated in the form of promises: "But we believe that through the grace of the Lord Jesus Christ we shall be saved… whoever calls upon the name of the Lord shall be saved" (Acts 15:11and Romans 10:13). These gospel promises are partaken of by faith."The just shall live by faith."
In addition to initial salvation, the good news of God's grace includes many other promises from God. "I will build My church…You shall know the truth, and the truth shall make you free…When He, the Spirit of truth, has come, He will guide you into all truth" (Matthew 16:18; John 8:32; and 16:13). All of these promises are experienced byfaith as well, because "the just shall live by faith"—continually, as well as initially.
