Answer
The book of Psalms is the praise book of the Bible, and it gives us hundreds of reasons why praise is important, as well as examples of how to give praise to God. In examining those reasons and examples, one thing becomes clear. “It is good to praise the LORD and make music to your name, O Most High...” (Psalm 92:1). Praise is a good thing. That means it is pleasant, valuable, and morally excellent. Psalm 147:1 tells us that praise is beautiful and agreeable.
When we consider the reasons why we should praise God, we find a list of His attributes. He is full of glory (Psalm 138:5), great (Psalm 145:3), wise and powerful (Daniel 2:20), good (Psalm 107:8), merciful and faithful (Psalm 89:1), and much more. This list of attributes is complemented by a list of His wonderful works. He is the One who saves us (Psalm 18:46), keeps His promises (1 Kings 8:56), pardons sin (Psalm 103:1-3), and gives us our daily food (Psalm 136:25). To try to list all the things God has done is impossible, but it is a wonderful exercise because it turns our hearts back to Him and keeps us mindful of how much we owe to Him.
Psalm 148:1-10 tells us that all of creation is commanded to give praise to God. When Jesus was entering Jerusalem on Palm Sunday, great crowds gathered and offered Him their praises. The Pharisees wanted Him to rebuke the people, but Jesus answered, “I tell you that, if these should hold their peace, the stones would immediately cry out” (Luke 19:40 KJV). Though there are many people who choose not to praise God right now, there is coming a day in which every knee will bow and every tongue will confess the praises of God (Philippians 2:10-11). Some will joyfully give those praises because of the salvation they have received, while some will give those praises as conquered enemies headed for eternal punishment for their rejection of God.
Praise is a vital part of a life surrendered to God, and it gives credit where credit is due. “O that men would praise the Lord for his goodness, and for his wonderful works to the children of men!” (Psalm 107:8 KJV).
