Conversación con Jesús

Dios mío, en vos deposito toda mi confianza

Tú lo sabes todo, Padre y señor del universo, eres Rey de los Reyes.

Tu que hiciste al paralítico caminar, al muerto volver a vivir, al

Leproso sanar. Tú que sabes de mis angustias y mis lágrimas, bien sabes.

Tú, mi amigo, cómo necesito alcanzar de Ti esta inmensa gracia. Al conversar

Contigo Maestro, me das ánimo y alegría para vivir, solamente de ti espero con

Fe y confianza. Haz, Divino Jesús, que antes de terminar esta oración, que seguiré

Con gozo durante 9 días, alcance esta inmensa gracia que te pido con fe.

Con gratitud publicaré esta oración para que otros que necesiten de Ti aprendan a

Tener fe y confianza en Tu misericordia. Ilumina mis pasos así como el sol, ilumina

Todos los días el amanecer, es testigo de nuestra oración, Jesús, confío en ti, cada

Vez más aumenta mi fe. Gracias por los favores recibidos.

Amén
