Here is a Jonathan Edwards quote for you:
I had great longings for the advancement of Christ’s kingdom in the world. My secret prayer used to be in great part taken up in praying for it. If i heard the least hint of anything that happened in any part of the world, that appeared to me, in some respect or other, to have a favorable aspect on the interest of Christ’s kingdom, my soul eagerly catched at it; and it would much animate and refresh me. I used to be earnest to read public news-letters, mainly for that end; to see if I could not find some news favorable to the interest of religion in the world.
That is zeal for the gospel. May we about building the kingdom.
