A gospel of Christ is also a gospel of obedience on our part:
in flaming fire taking vengeance on those who do not know God, and on those who do not obey the gospel of our Lord Jesus Christ. [SUP]9 [/SUP]These shall be punished with everlasting destruction from the presence of the Lord and from the glory of His power, (2 Thessalonians 2:8-9)
For the time has come for judgment to begin at the house of God; and if it begins with us first, what will be the end of those who do not obey the gospel of God? (1 Peter 4:17)
Moreover, brethren, I declare to you the gospel which I preached to you, which also you received and in which you stand, [SUP]2 [/SUP]by which also you are saved, if you hold fast that word which I preached to you—unless you believed in vain. (1 Corinthians 15:1-2)
if indeed you continue in the faith, grounded and steadfast, and are not moved away from the hope of the gospel which you heard, which was preached to every creature under heaven, of which I, Paul, became a minister. (Colossians 1:23)
But they have not all obeyed the gospel. For Isaiah says, “Lord, who has believed our report?” (Romans 10:16)
As we have said before, so now I say again, if anyone preaches any other gospel to you than what you have received, let him be accursed. (Galatians 1:9)
