Prayer is the overflowing of the heart in the presence of God.
— Madame Guyon

Groanings which cannot be uttered are often prayers which cannot be refused.
— Charles Haddon Spurgeon

Prayer is conversation with God.
— St. Clement of Alexandria

We will never have time for prayer, we must make time.
