It's often been pointed out by commentators that when the wise men brought gold to Jesus, it was actually being used by God to provide the funds necessary for Joseph to take the young child and his mother to Egypt to escape Herod's attempt on his life. This is probably true, but although it is true, it is overshadowed by the significance of the gift itself. Jesus Christ was a king. The wise men knew this, and hence their gift of gold pointed to his kingship.

The final answer that Psalm 150 gives to the questions you or I might have about worship is to tell us who should praise God. The answer is as comprehensive as those that have been given to each of the other questions we might have been asking. 

What an obvious flow of thought this final psalm has! After telling us where to praise God (in v. 1) and reminding us why we should praise him (in v. 2), the next three verses, exactly one-half of the psalm, tell us how God should be praised (vv. 3-5). 

It is time to make noise, praise-noise for God. Not all worship should be noisy, of course. There are psalms of lament that call for heart-rending sorrow by God's people. Other psalms call for quiet reflection on the acts of God in history, acts that are sometimes puzzling and even incomprehensible to us. But there are times for celebration too. When David brought the ark to Jerusalem, to the place he had prepared for it, the arrival of the ark was announced by trumpets and David danced with abandon before God (2 Sam. 6:14, 15). When the people praised God for the completion of the building of the walls of Jerusalem in Nehemiah's day, the sound of trumpets, cymbals, harps, lyres and singing was so loud that “the sound of rejoicing in Jerusalem could be heard far away” (Neh. 12:43; see vv. 27-44). 

In yesterday’s study, I concluded with the point that while Christians can serve as soldiers, they are not to try to advance the work of God by killing its enemies.
