I must be one of the few Christians who start grinding my teeth when a praise/worship song has the line "Our God Reigns"
Let me explain my reasons why and please keep in mind this is just my opinion and I respect that you may not share it or see things the same way. Respect then that this is how I see it.
Firstly it seems to divide people into 2 groups. There's 'our' group that sings about "our God" and then 'your' group that doesn't serve this God of mine or doesn't serve Him the same way. The attitude seems to be one of "This is my God, na-na-na-na, He is so much better than yours!"
It's gotten to the point where I have to rewrite the meaning in my head for it to mean, "God of all people; Of all the earth," even if there are people that have yet to meet or accept Him.
OUR GOD REIGNS
In my eyes, there is only one God, God of heaven and earth, creator, sustainer, consisting of Father, Son and Holy Spirit. One God. No competition.
So if you sing "Our God Reigns" who are you singing it to? Who are you trying to prove it to?
Why not just sing of your love for Him and extol His virtues. It will unite and invite, and not divide.
I know, I know, I'm different/strange/quirky. Thank you for bearing with me! :)
