I. Think what it is to praise the Lord. Praise is the heart singing. When the love of our hearts is set on Jesus, the gladness goes with us everywhere: at home or at school, at work or at play.
II. Notice some reasons why we should all thus praise the Lord. (1) Because He has loved us and given Himself for us. (2) We are the only creatures in the world that can praise Him. (3) Praise is the only thing we can give to the Lord. (4) Loving praise is the only thing that can satisfy our loving Lord. (5) Everybody ought to praise the Lord now, because it is the happy work that we shall do in heaven.
