"Let us offer the sacrifice of praise to God continually"- "continually" that is to say, without ceasing. Let us make an analogous precept to that which saith, "pray without ceasing," and say, "praise without ceasing."
Not only in this place or that place, but in every place, we are to praise the Lord our God. Not only when we are in a happy frame of mind, but when we are cast-down and troubled. The perfumed smoke from the altar of incense is to rise towards heaven both day and night, from the beginning of the year to the year's end.
