Psalm 145:21: My mouth shall speak the praise of the Lord: and let all flesh bless his holy name for ever and ever. (KJV).
It was David’s character or attitude to always use his mouth to praise the Living God. His life was not an easy-going kind when he was young. He was not the popular kid in his household. He was running from one town to another and from one cave to another when he was chased by king Saul. Such was the person who said that his mouth shall speak the praise of the Lord.
Praising God took David to an altogether different platform in his life. He became a king in God’s time. God said that he was a man after God’s own heart. Didn’t David sin? Yes, he sinned but repented of it and never sinned again. God is such a holy God, but He loves the praises of His people. In fact, David says let all flesh bless His holy name for ever and ever. Having tasted God’s love and protection over his life, David thought it is worthwhile to speak God’s praise. Blessing the holy name of God is universal. Not every mouth is dedicated to utter the praises of God. While some mouths speak profanity, let us use our mouths to glorify God irrespective of what situation we are in.
The Lord Jesus said that out of the abundance of the heart, the mouth speaks. So if our hearts treasure godly values and principles, our mouths will show it. God deserves all the praise, the glory, and the honor that is due Him.
