delirious?

Honestly, I am not a Christian; maybe a person without religion. I haven't figure out, or saying I haven't get a chance to know each religion.
A few days ago, my friend told me a guest band present in a conference she went to; and gave me the link of this band. I listened, enjoyed the song. quite interested! I think I heard it before. Here is one of their songs I like the most:
Did You Feel The Mountains Tremble?

Did you feel the mountains tremble?
Did you hear the oceans roar?
When the people rose to sing of
Jesus Christ the risen one

Did you feel the people tremble?
Did you hear the singers roar?
When the lost began to sing of
Jesus Christ the risen one

And we can see that God you're moving
A mighty river through the nations
And young and old will turn to Jesus
Fling wide your heavenly gates
Prepare the way of the risen Lord

Open up the doors and let the music play
Let the streets resound with singing
Songs that bring your hope
Songs that bring your joy
Dancers who dance upon injustice

Did you feel the darkness tremble?
When all the saints join in one song
And all the streams flow as one river
To wash away our brokeness

And here we see that God you're moving
A time of Jubilee is coming
When young and old return to Jesus
Fling wide your heavenly gates
Prepare the way of the risen Lord
