Make a joyful noise to the LORD, all the earth!   Psalm 100:1

Worship is a command not a request.  The psalmist does not say, “If it’s not too much trouble—if you have time, could you make a joyful noise to the Lord?”  He says, in the imperative, “MAKE A JOYFUL NOISE.”  This is a command.

Something we find all throughout the Scriptures is that God does not request worship, He demands it.  This means if we do not worship Him, we are being disobedient to Him.  To refuse to worship the Lord, is to refuse to do the very thing we were created and commanded by God to do. 

This is why we pray for those who do not know God and share our faith and do missions.  We do these things because there are people all around us and all around the world who are disobeying God by not worshiping Him and we are to go and tell them that.  We are to go and tell them that God has created all people for Himself and for His glory and that He demands that everyone everywhere give their lives up and over to Him and do all things under His authority and for His glory.
