"The concern for world evangelization is not something tacked on to a man's personal Christianity, which he may take or leave as he chooses. It is rooted in the character of the God who has come to us in Christ Jesus. Thus, it can never be the province of a few enthusiasts, a sideline or a specialty of those who happen to have a bent that way. It is the distinctive mark of being a Christian." -- James S. Stewart

And he said unto them, Go ye into all the world, and preach the gospel to every creature.--Jesus Christ

"Missionary zeal does not grow out of intellectual beliefs, nor out of theological arguments, but out of love" -- Roland Allen "

'Not called!' did you say?'Not heard the call,' I think you should say.
Put your ear down to the Bible, and hear Him bid you go and pull sinners out of the fire of sin. Put your ear down to the burdened, agonized heart of humanity, and listen to its pitiful wail for help. Go stand by the gates of hell, and hear the damned entreat you to go to their father's house and bid their brothers and sisters and servants and masters not to come there. Then look Christ in the face -- whose mercy you have professed to obey -- and tell Him whether you will join heart and soul and body and circumstances in the march to publish His mercy to the world. -- William Booth, founder of the Salvation Army

   How then shall they call on him in whom they have not believed? and how shall they believe in him of whom they have not heard? and how shall they hear without a preacher?

   And how shall they preach, except they be sent? as it is written, How beautiful are the feet of them that preach the gospel of peace, and bring glad tidings of good things! --Jesus Christ
