Psalm 146 begins with an introduction of praise, “Praise ye the LORD. Praise the LORD, O my soul.” (verse 1) This is an enthusiastic, heartfelt expression of praise. It seems to come from the innermost being of the Psalmist. David echoed the same in Psalm 103:1, “Bless the LORD, O my soul: and all that is within me, bless his holy name.” Remember what the words “praise” and “bless” mean? To praise means, “to make a show, boast, celebrate, commend.” To bless, when used in relationship to God, means, “an act of adoration, congratulate, kneel, praise, salute, thank.” Blessing and praising God brings Him very high honor. He is worthy of the highest honor. We should joyfully praise and bless Him with our whole being.
How long did the Psalmist plan to bless the Lord? He said, “While I live will I praise the LORD: I will sing praises unto my God while I have any being.” (Psalm 146:2) He planned to praise the Lord as long as He was alive, while he had any being. We see this same thing in Psalm 63:4, “Thus will I bless thee while I live: I will lift up my hands in thy name.” It is also seen in Psalm 104:33, “I will sing unto the LORD as long as I live: I will sing praise to my God while I have my being.” How long should God be praised? As long as we have any being, as long as we are alive. If we have breath and are able to talk, we should praise the Lord. Praise and blessing belong to God because He is worthy.
