Praising God is a spiritual sacrifice, an acceptable offering that pleases Him. By Him, Christ, let us continually offer the sacrifices of praise to God, that is, the fruit of our lips, giving thanks to His name. Praise is a form of spiritual worship that helps us stay focused on God. It was the continual responsibility of the Levitical priesthood to stand every morning to thank and praise the Lord, and likewise at evening. King David set an example by praising God seven times each day, teaching us to praise God continually or be prepared to do so at any time. Praise can be offered in various forms: singing, playing musical instruments, dancing, speaking, or praying. God enjoys them all, provided they are based upon spiritual truths and principles and presented in humility. As a spiritual sacrifice, praise is a specific duty that we, as a royal priesthood in training, are required to perform. We are a chosen generation, a royal priesthood, a holy nation, His own special people, that we may proclaim the praises of Him who called us out of darkness into His marvelous light. Offering up the spiritual sacrifice of praise to God is not to be taken lightly. It is our duty to offer praise continually with a sincere and dedicated attitude. We proclaim His virtues, showing the excellencies of all that He does. There are innumerable attributes and characteristics for which we may praise the Almighty God of heaven, such as the Eternal's purity and righteousness, the beauty of holiness, and His marvelous works in creation. We should praise Him for the power needed to create and sustain all of the physical and spiritual realm, for His uniqueness and faithfulness, for His name and His goodness, for His involvement in His plan of salvation, and for revealing to us His Word. The number of things for which we can praise the Eternal God is unlimited. Our mental attitude is critically important in properly praising the Eternal; without the right attitude, our praises are unacceptable to the Almighty, but acceptable sacrifices of praise are pleasing to God. The spiritual sacrifice of praise is an act of offering to God acknowledgment of His attributes, an act of spiritual worship that helps us to stay focused on Him. Our duty as a royal priesthood is to continually offer the spiritual sacrifice of praise to God. Praising God is so important that it stands as a dominant theme, and we have so many reasons to praise our holy and righteous God.
