WHY DO WE HAVE a call to worship?
Praise the Lord, all nations! Glorify him, all peoples! For his faithful love to us is great; the Lord’s faithfulness endures forever. Hallelujah! – Psalms 117:1-2
We come from a long line of people who are restlessly prone to wander. The heart is a fickle thing and needs to be tuned regularly. The call to worship serves as a tuning of our hearts.
God Calls Us to Worship
There is a quiet reminder in the call to worship that worship is not our idea. We worship because it is God’s idea. Psalm 117 is God’s word, which means it is God who is speaking to his people, commanding, inviting, and exhorting us to praise him (verse 1). This call is rooted in a firm commitment to both his glory and our joy. When God’s people are gathered in his name, he serves as the host. He has initiated and invited us into fellowship with him.
The Response of Worship
The response in Psalm 117 implies a recognition of who God is — of his worth (verse 2). In the call to worship we recognize and remember that it is God alone who is worthy to have our hearts, lips, and lives. As truth rings through our bones, we are reminded of the object of our worship. Worship, in the rhythm of revelation and praise, begins with God making himself known, and is followed by our response of remembrance and praise.
This response of worship in Psalm 117 is one rooted in who God has revealed himself to be. The psalmist’s worship is informed. Likewise, we praise and exhort God because he has revealed himself to us in his word. We worship him because of the beauty of his character. He is the God who has fixed his love upon us as his chosen people. He is the God whose faithfulness cannot be exhausted. He is the God who is worthy of worship from every tribe, tongue, people, and nation. Our theology leads to doxology.
Hear the Call
The next time a worship service begins — even today — pay close attention to the invitation that rings through the air. We are called not because of our righteousness, our works, or our piety. We are welcomed because God has chosen us, Christ has purchased us, and the Holy Spirit has sealed us for eternity. This call is for the weak and the weary, the poor and the helpless. The call to worship is a call to come and drink deeply from the well that will never run dry.
Come, everyone who is thirsty, come to the water; and you without silver, come, buy, and eat! Come, buy wine and milk without silver and without cost! – Isaiah 55:1
