This song is in Spanish, but it brings me to tears and down on my knees every time I hear it.
I translated the lyrics below:
I want to be a light to the nations
I want to be salt and to change the world
Show me Your glory,
tell me about the history of your magnificent love
Shine in me
I want to go
That the world would proclaim that You are King
Light my heart with Your love
Shine in me
Send me
Guide my steps
I will follow
In Your name I will go,
Shine in me
Put Your health in my hands
Give my heart Your love
If we don't show them
If we don't proclaim
How will they know Your love?
