“Consider the following classic example of a call to worship from Psalm 95:1-5:
1 Oh come, let us sing to the LORD;
let us make a joyful noise to the rock of our salvation!
2 Let us come into his presence with thanksgiving;
let us make a joyful noise to him with songs of praise!
3 For the LORD is great God,
and a great King above all gods.
4 In his hand are the depths of the earth;
the heights of the mountains are his also.
5 The sea is his, for he made it,
and his hands formed the dry land.
In verses 1-2, we see a proliferation of imperatives in which God summons his people to worship: come, sing, make a joyful noise. Verses 3-5 provide the basis for this activity: the Lord is a great God and King, the Creator, Sustainer, and Governor of all things. The imperatives, summoning God’s people to worship, are grounded in a theological rationale, stating who God is and what he has done for his own people.”
