The greatest thing anyone can do for God or man is pray.

Prayer strikes the winning blow; service is simply picking up the pieces.

Prayer is partnership with God in His planet-sized purposes, and includes the "all things" beside, as an important detail of the whole.

God's greatest agency; man's greatest agency, for defeating the enemy and winning men back is intercession.

The greatest thing anyone can do for God and for man is to pray. You can do more than pray after you have prayed, but you cannot do more than pray until you have prayed. Prayer is striking the winning blow ... service is gathering up the results.

The greatest thing anyone can do for God and man is pray. It is not the only thing; but it is the chief thing. The great people of the earth today are the people who pray. I do not mean those who talk about prayer; not those who can explain about prayer; but I mean those people who take time and pray.

Prayer is repeating the victor's name (Jesus) into the ears of Satan and insisting on his retreat.
