Let us live as people who are prepared to die, and die as people who are prepared to live.
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.
The gospel is a declaration, not a debate.
