Richard Baxter on Laboring Against Hard-Heartedness Through Prayer

“Labour hard with your hearts all the while to keep them in a reverent, serious, fervent frame, and suffer them not to grow remiss and cold, to turn prayer into lip-labour, and in lifeless formality . . . when the heart is senseless, though the voice be earnest. The heart will easily grow dull, and customary, and hypocritical, if it be not carefully watched, and diligently followed and stirred up.” (Richard Baxter)
