Nuestro Juramento is a sweeping declaration of love that refuses to be limited by time, sorrow, or even death. Juanes sings as a devoted partner who cannot bear to see his beloved in tears; her sadness "kills" him and fills his heart with anguish. To chase away any doubts, he recalls the solemn promise they have made: to love each other until death, and—if the dead can love—beyond.
The song then imagines two haunting yet tender scenarios. If he dies first, he urges her to cry over his body so the whole world sees the depth of her love. If she dies first, he pledges to write their love story with the very blood from his heart, turning grief into an everlasting testament. In just a few verses, Juanes transforms heartache into poetic devotion, painting a portrait of love so intense that it outlasts life itself.
