He who would preach powerfully must pray effectively.
There can be no prevailing in prayer without travailing in prayer.
The light that shines the farthest will shine the brightest at home.
No one has the right to hear the gospel twice, while there remains someone who has not heard it once.
We talk of the second coming, half the world has never heard of the first.
The supreme task of the church is the evangelization of the world. No one has the right to hear the gospel twice until everyone has had an opportunity to hear it at least once.
