O, my soul, praise God with the best instrument, the heart, and let the instrument be screwed up to the highest, do it with the whole heart. When God is tuning upon the string of mercy, a Christian should be tuning upon the string of praise.
Let us sing unto the Lord a new song. It is a holy duty to sing praises to God, with understanding and with the heart, for this is a part of the worship of the true God.
Conceive of this duty of praising God according to its superlative excellencies as being the highest service that the tongue of men or angels can perform. To bless or praise or magnify God is not to make Him greater or better or happier than He is, but to declare and extol His greatness, goodness, and felicity. Practical Works
God's praise is too big for the heart; acknowledge all therefore privately in thy prayers to God, and not only so but also to others. When God had delivered the Israelites, Moses tells Jethro what He had done for them (Ex. 18:8). David bids them come to him, and he would tell them what He had done for his soul. Christ's reward of the leper for healing him was, "Go and tell what is done for thee." Instead of foolish jesting, which our mouths are full of, rather give thanks (Eph. 5:4); and if the heart were full, the mouth would be filled with praise. Works
