Psalms 57:8

By lively faith, David's prayers and complaints are at once turned into praises. His heart is fixed; it is prepared for every event, being stayed upon God. If by the grace of God we are brought into this even, composed frame of mind, we have great reason to be thankful. Nothing is done to purpose, in religion, unless it is done with the heart. The heart must be fixed for the duty, put in frame for it; fixed in the duty by close attention. Our tongue is our glory, and never more so than when praising God; dull and sleepy devotions will never be acceptable to God. Let us awake early in the morning, to begin the day with God; early in the beginning of a mercy. When God comes toward us with his favours, let us go forth to meet him with our praises. David desired to bring others to join in praising God; and in his psalms, he is still praising God among the people, singing to Him among the nations. Let us seek to have our hearts fixed to praise his boundless mercy and unfailing faithfulness; and to glorify him with body, soul, and spirit, which are his. Let us earnestly pray that the blessings of the gospel may be sent through every land.

Awake up, my glory. Let the noblest powers of my nature bestir themselves: the intellect which conceives thought, the tongue which expresses it, and the inspired imagination which beautifies it —let all be on the alert now that the hour for praise has come. Awake, psaltery and harp. Let all the music with which I am familiar be well attuned for the hallowed service of praise. I myself will awake early. I will awake the dawn with my joyous notes. No sleepy verses and weary notes shall be heard from me; I will thoroughly arouse myself for this high employ. When we are at our best we fall short of the Lord's deserts, let us, therefore, make sure that what we bring him is our best, and, if marred with infirmity, at least let it not be deteriorated by indolence. Three times the psalmist calls upon himself to awake. Do we need so much arousing, and for such work? Then let us not spare it, for the engagement is too honourable, too needful to be left undone or ill done for want of arousing ourselves.
