It is not left to our own option whether or not we will praise God. Praise is God's most righteous due, and every Christian, as the recipient of His grace, is bound to praise God from day to day.
It is true that we have no authoritative text for daily praise; we have no commandment prescribing certain hours of song and thanksgiving: But the law written upon the heart teaches us that it is right to praise God; and the unwritten mandate comes to us with as much force as if it had been recorded on the tables of stone or handed to us from the top of thundering Sinai.
Yes, it is the Christian's duty to praise God. It is not only a pleasurable exercise, but it is the absolute obligation of his life. Those of you who are always mourning should not think that you are guiltless in this respect or imagine that you can discharge your duty to God without songs of praise. You are bound by the bonds of His love to bless His name as long as you live, and His praise should continually be in your mouth, for you are blessed in order that you may bless Him--"the people whom I formed for myself that they might declare my praise";1 and if you do not praise God, you are not bringing forth the fruit that He has a right to expect from you.
Do not let your harp hang on the willows, but take it down and strum with a grateful heart, bringing out its loudest music. Arise and declare His praise. With every morning's dawn, lift up your notes of thanksgiving, and let every setting sun be followed with your song. Surround the earth with your praises; circle it with an atmosphere of melody, and God Himself will listen from heaven and accept your music.
E'en so I love Thee, and will love,
And in Thy praise will sing,
Because Thou art my loving God,
And my redeeming King.
