Looking for lyrics

I am looking for the lyrics to two songs by Martin Mancilla. The first one is: QUIEN ESTA EN TI, and the second is: AMAR A DIOS. If anyone knows the lyrics or can tell me where to find them, that would be awesome! I have a missions trip to Machala, Ecuador in July.....and my group really needs to practice!! Thanks!!!

Hello again! I am also looking for the song "Quien esta en Ti" by Carman. I cannot seem to find the lyrics to this song anywhere!!!

I found no singer called Martin Mancilla on the net.
