When Paul said, “In whom the god of this world hath blinded the minds of them which believe not, lest the light of the glorious gospel of Christ, who is the image of God, should shine unto them … For God, who commanded the light to shine out of darkness, hath shined in our hearts” (2Co 4:4,6), he was revealing the mystery of the gospel hidden since the beginning, “darkness was upon the face of the deep. And the Spirit [breath] of God moved upon the face of the waters. And God said, Let there be light: and there was light.” (Gen 1:2-3). This literal, historic event was figurative and prophetic of what would come—mankind’s minds would be blind and hearts dark but God would send His Son to preach the “light” of His gospel. The gospel is the message God’s Son was sent to preach. There’s no other gospel.
Christ’s 12 apostles, including Paul, were all saved by His gospel message. And the gospel they took to the world is the message they learned from Him. There’s no disagreement or disconnect whatsoever in the message they all preached. Paul said he learned the gospel from Christ Himself, “But I certify you, brethren, that the gospel which was preached of me is not after man. For I neither received it of man, neither was I taught it, but by the revelation of Jesus Christ.” (Gal 1:11-12). And he was unashamed to preach the same gospel Christ preached, “For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to every one that believeth [trusts]” (Rom 1:16), “Now to him that is of power to stablish you according to my gospel, and the preaching of Jesus Christ” (Rom 16:25).
The gospel is everything Jesus Christ taught and preached collectively. The gospel can’t be compartmentalized apart from other subjects—as it’s done today—because it’s composed of everything Jesus preached. What Christ taught about God, Himself, mankind, righteousness, eternal life, judgment, and the last days is the gospel. It’s not “Steps to Peace with God” or the “Romans Road to Salvation.”
Jesus told a Samaritan woman, “Ye worship ye know not what: we know what we worship: for salvation is of the Jews. But the hour cometh, and now is, when the true worshippers shall worship the Father in spirit [breath] and in truth: for the Father seeketh such to worship him. God is a Spirit: and they that worship him must worship him in spirit [breath] and in truth.” (Jhn 4:22-24). The Samaritans were the closest people to the Jews yet even they weren’t saved because they didn’t know and worship the true God. We must worship the true God to be saved. Nobody but the only begotten Son has seen God, “No man hath seen God at any time; the only begotten Son, which is in the bosom of the Father, he hath declared him” (Jhn 1:18). Therefore, what He said about God is the truth and the only way of eternal life, “And this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent” (Jhn 17:3). There’s no other gospel.
Christ taught that we must live righteously to enter the kingdom, “That except your righteousness shall exceed the righteousness of the scribes and Pharisees, ye shall in no case enter into the kingdom of heaven” (Mat 5:20). And that He will deny entrance to those breaking God’s laws, “I never knew you: depart from me, ye that work iniquity” (Mat 7:23), “you lawbreakers!” (NET), “you who practice lawlessness!” (NKJV), “you who break God’s laws” (NLT). In His last words to us, “Blessed are they that do his commandments, that they may have right to the tree of life, and may enter in through the gates into the city” (Rev 22:14).
John stated, “And hereby we do know that we know him, if we keep his commandments. He that saith, I know him, and keepeth not his commandments, is a liar, and the truth is not in him.” (1Jo 2:3-4). It’s not “believers” but those keeping His commandments that know Him. Those transgressing or not abiding in what Christ taught, don’t have God, “Whosoever transgresseth, and abideth not in the doctrine of Christ, hath not God. He that abideth in the doctrine of Christ, he hath both the Father and the Son.” (2Jo 1:9). There’s no other gospel.
“And Jesus went about all Galilee, teaching in their synagogues, and preaching the gospel of the kingdom” (Mat 4:23), “And Jesus went about all the cities and villages, teaching in their synagogues, and preaching the gospel of the kingdom” (Mat 9:35), “And this gospel of the kingdom shall be preached in all the world for a witness unto all nations; and then shall the end come” (Mat 24:14). So called evangelistic organizations track how many people groups in the world today are still unreached. The fact is, they all are! None have been reached with “this gospel of the kingdom” Jesus Christ preached. What’s being preached today is a god in three persons, a heavenly destiny of man, and salvation by believing some facts are true.
The gospel is the message God’s Son preached—everything He preached! But if we won’t listen to Him, we have no hope and we’ll perish. There’s no other gospel.
