People need to hear of the old liberating power of the gospel, which saves sinners and sets them right with God. We do not preach a new thing but the timeless crucified Savior Who will never change, though the world and its trends come and go like the tide.
Rom 1:14 I am debtor both to the Greeks, and to the Barbarians; both to the wise, and to the unwise.
Rom 1:15 So as much as is in me, I am ready to preach the gospel to you that are at Rome also.
Rom 1:16 For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to every one that believes; to the Jew first, and also to the Greek.
Rom 1:17 For therein is the righteousness of God revealed from faith to faith: as it is written. The just by faith shall live.
Rom 1:18 For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men."
Paul shows us that the gospel is for all people in every place and for all time. He makes this immense statement: "I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to everyone that believes..."
Question: Why was Paul not ashamed of the gospel?
Answer: Because it is powerful; it is the power of God unto salvation.
The gospel, and it alone, though the world despises and ridicules it, is the only power [force, ability, strength] in heaven and on earth that can save men. If any man, Jew or Gentile, ancient or modern, is to be saved, it must be by the gospel, for there is nothing else in heaven or on earth that is able to save them. "There is no other 'detergent' that can remove this kind of stain, and though the world mock the look of it, I'm not ashamed, because this is the only thing that works, and nothing else! You can laugh at it and hate it, but it will cleanse the stain. You can ridicule the gospel, and mock me it's preacher, but I will preach on without shame, because the gospel, and this alone, is the only power in the whole world that can save sinners."
Question: Why is the gospel powerful? Why is it the power of God unto salvation?
Answer: Because in it the righteousness of God is revealed from faith to faith.
Why and how does the gospel save? What is it's power? The answer is explicitly given in verse 17. The reason that the gospel is the power of God unto salvation is because in it, and in it alone, is the righteousness of God revealed. The righteousness of God is shown to sinful men through the gospel, and it is the righteousness of God that saves us. What is the righteousness of God that is shown in the gospel? Later in the Book of Romans Paul explains that this is the righteousness that God has provided, in Christ, for undeserving sinners (Rom. 3:21-30, 5:15-21). In other words, what is revealed to men in the gospel is God's gift of righteousness in Christ that is ours for the taking by faith, ("from faith to faith" means "faith from first to last", or, "totally by faith alone"). Paul introduces us to "the righteousness of God by faith" by contrasting it with the "righteousness of the law": "But now the righteousness of God without the law is manifested, being witnessed by the law and the prophets; Even the righteousness of God which is by faith of Jesus Christ unto all and upon all them that believe." (Rom. 3:21-22) This is exactly why the gospel is the power of God unto salvation, for it reveals to men the only way for them to be righteous before God: not by their own works, obedience and good works, but by faith in Jesus Christ. When a sinner places his trust in Jesus Christ and the atoning sacrifice that He made on his behalf, righteousness is given "unto" or "upon" him, and he is declared to be righteous in the sight of God. All the righteousness a man needs to be right with God was secured by the blood of Christ on the cross - who died for our sins, paying the just penalty our sins deserve - and by believing in Christ a person receives that free gift of righteousness. Believers are righteous before God, and will pass judgment day with flying colors to live with God forever. Paul points out that God had affirmed this all before in the prophets: "The just [or righteous] by faith shall live." The gospel saves because the gospel makes men righteous before God.
Question: Why do men need righteousness?
Answer: Because the wrath of God is against all the unrighteousness of men.
Verse 18 explains the universal need of salvation by righteousness. We do not need saving from a boring life. We do not need saving from drowning in a lake. We do not need saving from emptiness or poverty. What all men, everywhere, in every age of time need, is saving from the wrath of God. "For the wrath of God is revealed from heaven against all the unrighteousness and ungodliness of men..." Paul goes on to show that every single person, without any exception, is an offender against God and is justly condemned to die under the righteous wrath of God. God punishes unrighteousness, and all men are unrighteous. "There is none righteous, no not one" (Rom. 3:10) "Therefore by the deeds of the law there shall no flesh be justified in his sight." (Rom. 3:20) If this is the case, what then can save them? How can man be righteous and thereby saved from the wrath of God? Not by our own good works. Not by prayers. Not by penance. There is only one thing that has the power to save sinners! It is the only thing that can make people righteous: the gospel of Jesus Christ! The Lord Jesus Christ died on a cross and paid the price for our sins, condemning unrighteousness in His body, and having risen from the dead, He freely offers righteousness to all who believe. Righteousness is the whole issue of salvation: God is righteous, and a person must be righteous to live in accordance with Him. All unrighteousness is impartially condemned by God, and because all are unrighteous, all are condemned. How then shall man and God be reconciled? Through the gospel of Jesus Christ! Here only is the way of reconciliation known and effected. Jesus Christ, the Righteous One, died for our sins so that all who believe will be declared righteous in the sight of God. (2 Cor. 5:21, 1 Peter 3:18, 1 John 2:1-2) This is the gospel, and it alone is the power of God to save sinners.
Here lies the simplicity of the gospel, and we must never forget it or replace it. The Church needs to shamelessly point men and women to the only place where they can go to be saved from the wrath of God. That is to Jesus Christ and Him crucified. Let us remember that what is truly needful isn't new doctrines and better programs and ear-tickling prophesies, promising people things that God never promised; but only one thing is needful, and that is the declaration of the gospel of Jesus Christ to a world of unrighteousness condemned by God. But I think a further question is necessary at this point:
Question: Why did God even provide the gospel?
Answer: Because God so loved the world.
The gospel reveals to us that God loves sinners, and He loves them so much that He gave His only begotten Son to die for them. If we withhold preaching the gospel to people because we are ashamed of its message, or don't want to offend, or would rather preach something more acceptable and inoffensive, we are actually robbing men and women of the true knowledge of the love of God in Christ Jesus, and robbing God of the glory He is worthy of. We are robbing both men and God by not preaching the gospel. This is why it is so important that we first of all understand the gospel, that we might preach it boldly as we ought. Consider what is at stake.
Let us who are Christians, as debtors with the apostle Paul, declare with timeless conviction, for God and man's sake: "I am not ashamed of the gospel of Christ."
If you are not a Christian, the question you must face is:
Question: Will you believe or disbelieve the gospel of Christ that has just been explained to you?
