Our Song Is Our Evangelism

Psalm 40: 1-3

I waited patiently for the Lord;
He inclined to me and heard my cry.
He drew me up from the pit of destruction,
out of the miry bog,
and set my feet upon a rock,
making my steps secure.
He put a new song in my mouth,
a song of praise to our God.
Many will see and fear,
and put their trust in the Lord.

And what about the secular city, the nations, the people who do not rejoice in God and do not know his salvation through Christ? Does our mission free the future for them?

The answer is found in verse 3: "He put a new song in my mouth, a song of praise to our God; many will see and fear, and will trust in the Lord."

There they are. Our joy, our gladness in God is the great mirror in the telescope for the nations and for the neighbors.

God saves me from the miry clay. He makes me secure. He puts a new song in my mouth. He makes himself the feast of my joy.

And what happens: "Many will see and fear, and will trust in the Lord."

Our song is our evangelism. Our passion for God is our persuasion for the nations.

When we are satisfied in God, he will be magnified in others. That's exactly what David says. We will sing and many will see and fear and put their trust in the Lord.

So our joy in God is both our worship and our evangelism. Our mission is to be a Christian Kitt Peak Observatory at the center of the city. We are called to seek God—to see him in the telescope of his Word. And we are called to rejoice and be glad in what we see—to have a new song of praise to our God—that's worship.

And out of that worship flow missions and evangelism as we show the power and love and wisdom of God, and welcome the nations and the neighbors to join us in our joy.
