Last week, I was thumbing through the Urbana '18 songbook (which is available here), and I stumbled across this worship song in Spanish. Written by Federico Pagura and Homero Perera and believed originally to be from Argentina, you can learn more about the story behind the song here. The melody may seem a bit verbose to sing at first, but the song's structure is very straight forward and has plenty of vocal harmony opportunities. And the words are very meaningful, speaking holistically about God's past, present and future work, and how it gives us hope and confidence.
