I Chronicles 15:16-22, "And David spake to the chief of the Levites to appoint their brethren to be the singers with instruments of musick, psalteries and harps and cymbals, sounding, by lifting up the voice with joy. So the Levites appointed Heman the son of Joel; and of his brethren, Asaph the son of Berechiah; and of the sons of Merari their brethren, Ethan the son of Kushaiah; And with them their brethren of the second degree, Zechariah, Ben, and Jaaziel, and Shemiramoth, and Jehiel, and Unni, Eliab, and Benaiah, and Maaseiah, and Mattithiah, and Elipheleh, and Mikneiah, and Obededom, and Jeiel, the porters. So the singers, Heman, Asaph, and Ethan, were appointed to sound with cymbals of brass; And Zechariah, and Aziel, and Shemiramoth, and Jehiel, and Unni, and Eliab, and Maaseiah, and Benaiah, with psalteries on Alamoth; And Mattithiah, and Elipheleh, and Mikneiah, and Obededom, and Jeiel, and Azaziah, with harps on the Sheminith to excel. Chenaniah, chief of the Levites, was for song: he instructed about the song, because he was skilful.

Psalms, a book comprised of and written entirely for the praise and worship of God, is the longest book of the Bible and has been placed as the center of not only the book itself but the center of every believers life.

Much of Psalms was written by David; however, after David appointed the Levites to minister praise and  music before the the arc of the Lord much of the Psalms were written for Asaph and his sons as they ministered. These Psalms were used chiefly during daily worship as well as the celebration of the Sabbath and the Feasts appointed by the Lord. Songs of praise passed down from generation to generation recording the mighty works of God in times of trouble and in times of joy.

Psalms 150:1-6, "Praise ye the LORD. Praise God in his sanctuary: praise him in the firmament of his power. Praise him for his mighty acts: praise him according to his excellent greatness. Praise him with the sound of the trumpet: praise him with the psaltery and harp. Praise him with the timbrel and dance: praise him with stringed instruments and organs. Praise him upon the loud cymbals: praise him upon the high sounding cymbals. Let every thing that hath breath praise the LORD. Praise ye the LORD."

If ever a book were written to the glory of God Psalms is that book. Within it's words it reveals the power of God, the majesty of God, and the mystery of God. Through Psalms we not only see what God has done in the life of mankind but we also see prophesy fulfilled in the One called the Messiah.

Psalms reveals the very nature of God, His character, and His desire toward mankind. He is the author and finisher of our faith, the Alpha and the Omega. He is the One Who restores health to our body, soul, and spirit. The One Who reigns above all things. He is our savior, our protector, and our provider. He is the One Who builds kingdoms and brings them down, but His kingdom is an everlasting kingdom that will never be destroyed.

Through the words of this book we can find comfort in every situation and be restored with the joy of the Lord which is our strength. Through praise and worship the power of God is released in our lives and manifested in ways that are to the glory of God, the King of glory, the Lord mighty in battle.  Creator of all things in both heaven and earth.
