Our God is a missionary God. He sent his Son to die for us. He sends his Spirit to restore us. And he sends us, his people, to the nations.
This prayer from Psalm 67  asks God to bless the nations through us.

May God be gracious to us and bless us
and make his face to shine upon us, Selah
2 that your way may be known on earth,
your saving power among all nations.
3 Let the peoples praise you, O God;
let all the peoples praise you!

4 Let the nations be glad and sing for joy,
for you judge the peoples with equity
and guide the nations upon earth. Selah
5 Let the peoples praise you, O God;
let all the peoples praise you!

:6 The earth has yielded its increase;
God, our God, shall bless us.
7 God shall bless us;
let all the ends of the earth fear him!
