These verses show that the gospel is the means or the vehicle that God uses to save us as long as we live by faith.

We cannot let the idea of "power" slide by without comment. From this Greek word, dunamis, English derives the words "dynamite," "dynamo," and "dynamic"—all of which convey an idea of stored energy that is waiting for the cue to burst into action, sometimes explosively! The gospel Jesus Christ preached contains a dynamic message that is primed to propel a believer to eternal life!

Notice, however, that the gospel is not universal in its application. John 6:44 says that the Father calls specific people to the choice of accepting Christ's gospel. In Romans 1:16, Paul makes this same distinction in the phrase "everyone who believes." The gospel will not save even those who profess Christ if they do not believe. As Christ's disciples, we must believe what He teaches us (compare John 6:28-29, 63).

What is belief? Jesus answers in Matthew 7:21: "Not everyone who says to Me, 'Lord, Lord,' shall enter the kingdom of heaven, but he who does the will of My Father in heaven." Paul says in Romans 16:25-26: "Now to Him who is able to establish you according to my gospel and the preaching of Jesus Christ, according to the revelation of the mystery kept secret since the world began but now has been made manifest . . . for obedience to the faith. . . ." He also writes in Hebrews 5:9: "And having been perfected, [Christ] became the author of eternal salvation to all who obey Him." Simply put, belief is not just agreement with Christ, but also doing what He says. If a person truly believes Christ, he will live like Him. (Faith, belief, obedience, and doing God's will are all intricately related concepts.)

This is why Paul continues as he does in Romans 1:17: "For in it [the gospel] the righteousness of God is revealed from faith to faith; as it is written, 'The just shall live by faith.'" The gospel teaches us what righteousness—right doing—is. God reveals it to us by faith so that we can be faithful ourselves. Succinctly, the gospel instructs us in doing or living what is right, godly, and faithful. As he puts it in II Corinthians 5:7, "We walk by faith, not by sight."

From this, we can see that the gospel is far more than "believe in name of Jesus, and you shall be saved" (an oversimplification of Acts 4:12).
