Sing the glory of His name; Make His praise glorious.
"...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;" and if you do not praise God, you are not bringing forth the fruit that He has a right to expect from you.
"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."
