True worship involves every aspect of one's being.  I went to a four-year Christian College for my bachelor's degree, and the school motto was "Head, Heart, and Hand."  A recognition that worshipping God involved the whole person.  Worship is not just an emotional release; it's an understanding of how much God has done for us, and a dedication of the head, the heart, and the hand to proclaim His name to succeeding generations.

1 Chronicles 16:8-13 records the "worship service" led by King David, and exhort us to respond to God's blessings in appropriate ways:  "Give thanks unto the LORD, call upon his name, make known his deeds among the people.  (9)  Sing unto him, sing psalms unto him, talk ye of all his wondrous works.  (10)  Glory ye in his holy name: let the heart of them rejoice that seek the LORD.  (11)  Seek the LORD and his strength, seek his face continually.  (12)  Remember his marvellous works that he hath done, his wonders, and the judgments of his mouth;  (13)  O ye seed of Israel his servant, ye children of Jacob, his chosen ones." (1 Chronicles 16:8-13.)    

Worship is vocal.  The mouth, the tongue, to vocal chords, the diaphragm are as much "instruments of praise" as the musical instruments noted in my last post.  The ear is involved, making sure we are "on pitch."  God created us for excellence, and excellence is what we ought to strive for.  However, if some of us are "tone deaf," that doesn't mean we shouldn't worship!  God never said, "Make a joyful melody unto the Lord."  He didn't say, "Make a joyful harmony unto the Lord."  Scripture tells us, "make a joyful noise."  Not once, not twice . . . but SEVEN times, we are encouraged to do so.  I can do that.

Worship is rememberable. That is, it has a body of historical recollections upon which to draw for content in our worship.  David encouraged the congregation, "talk of all His wondrous works; REMEMBER His marvellous works, His wonders, the judgments of His mouth."  There's a reason they were to sing. . . and we have reason to sing, as well.  "Count your many blessings, name them one by one; and it will surprise you what the Lord has done!"

Finally, worship is personal.  This worship service was comprised of those who belonged to the Lord, who had experienced His faithfulness to all generations, who had worked His mighty wonders in their very midst.  The congregation was comprised of "the seed of Israel His servant," and "children of Jacob, His chosen ones."  They are the only ones who could sing this song.  If a Philistine or a Moabite had tried to sing this song, there would have been problems.  You can't sing a song like this if you haven't experienced the lyrics firsthand.
