Grace breeds delight in God, and delight breeds meditation. Meditation is a duty wherein consists the essentials of religion, and which nourishes the very life-blood of it. That the Psalmist may show how much the godly man is habituated to this blessed work of meditation, he subjoins, 'In his law does he meditate day and night;' not but that there may be sometimes intermission: God allows time for our calling, he grants some relaxation; but when it is said, the godly man meditates day and night, the meaning is, frequently-he is much conversant in the duty.
