Give me one hundred preachers who fear nothing but sin and desire nothing but God, and I care not whether they be clergymen or laymen, they alone will shake the gates of Hell and set up the kingdom of Heaven upon Earth.
We need to proclaim the Gospel on every street corner, preaching the good news of the kingdom and healing, even with our preaching, every kind of disease and wound.
Apostolic preaching cannot be carried on unless there be apostolic prayer. Men of God, before anything else, are indispensable to the furtherance of the kingdom of God on earth.
It is the childlike mind that finds the kingdom.
Preaching is to much avail, but practice is far more effective. A godly life is the strongest argument you can offer the skeptic.
