I have been constantly on the move. I have been in danger from rivers, in danger from bandits, in danger from my own countrymen, in danger from Gentiles; in danger in the city, in danger in the country, in danger at sea; and in danger from false brothers. I have labored and toiled and have often gone without sleep; I have known hunger and thirst and have often gone without food; I have been cold and naked. Besides everything else, I face daily the pressure of my concern for all the churches. Who is weak, and I do not feel weak? Who is led into sin, and I do not inwardly burn? If I must boast, I will boast of the things that show my weakness. The God and Father of the Lord Jesus, who is to be praised forever, knows that I am not lying.
If there be any one point in which the Christian church ought to keep its fervor at a white heat, it is concerning missions. If there be anything about which we cannot tolerate lukewarmness, it is in the matter of sending the gospel to a dying world. –C.H. Spurgeon
