'Good News' in the Bible

Now when I came to Troas for the good news of Christ, and there was an open door for me in the Lord,

But if our good news is veiled, it is veiled from those who are on the way to destruction:

Because the god of this world has made blind the minds of those who have not faith, so that the light of the good news of the glory of Christ, who is the image of God, might not be shining on them.

And with him we have sent a brother whose praise in the good news has gone through all the churches;

For when, through this work of giving, they see what you are, they give glory to God for the way in which you have given yourselves to the good news of Christ, and for the wealth of your giving to them and to all;

For we have no need to make ourselves seem more than we are, as if our authority did not come as far as to you: for we came even as far as you with the good news of Christ:

So that we may be able to go on and take the good news to countries still farther away than you are, and not take credit for another man's work in making things ready to our hand.

For if anyone comes preaching another Jesus from the one whose preachers we are, or if you have got a different spirit, or a different sort of good news from those which came to you, how well you put up with these things.

Or did I do wrong in making myself low so that you might be lifted up, because I gave you the good news of God without reward?
