1 That which was from the beginning, that which we have heard, that which we have seen with our eyes, that which we saw, and our hands touched, concerning the Word of life 2 (and the life was revealed, and we have seen, and testify, and declare to you the life, the eternal life, which was with the Father, and was revealed to us); 3 that which we have seen and heard we declare to you, that you also may have fellowship with us. Yes, and our fellowship is with the Father and with his Son, Jesus Christ. 4 And we write these things to you, that our joy may be fulfilled.

5 This is the message which we have heard from him and announce to you, that God is light, and in him is no darkness at all. 6 If we say that we have fellowship with him and walk in the darkness, we lie and don’t tell the truth. 7 But if we walk in the light as he is in the light, we have fellowship with one another, and the blood of Jesus Christ his Son, cleanses us from all sin. 8 If we say that we have no sin, we deceive ourselves, and the truth is not in us. 9 If we confess our sins, he is faithful and righteous to forgive us the sins and to cleanse us from all unrighteousness. 10 If we say that we haven’t sinned, we make him a liar, and his word is not in us.

1 LO que era desde el principio, lo que hemos oído, lo que hemos visto con nuestros ojos, lo que hemos mirado, y palparon nuestras manos tocante al Verbo de vida;

2 (Porque la vida fué manifestada, y vimos, y testificamos, y os anunciamos aquella vida eterna, la cual estaba con el Padre, y nos ha aparecido;)

3 Lo que hemos visto y oído, eso os anunciamos, para que también vosotros tengáis comunión con nosotros: y nuestra comunión verdaderamente es con el Padre, y con su Hijo Jesucristo.

4 Y estas cosas os escribimos, para que vuestro gozo sea cumplido.

5 Y este es el mensaje que oímos de él, y os anunciamos: Que Dios es luz, y en él no hay ningunas tinieblas.

6 Si nosotros dijéremos que tenemos comunión con él, y andamos en tinieblas, mentimos, y no hacemos la verdad;

7 Mas si andamos en luz, como él está en luz, tenemos comunión entre nosotros, y la sangre de Jesucristo su Hijo nos limpia de todo pecado.

8 Si dijéremos que no tenemos pecado, nos engañamos á nosotros mismos, y no hay verdad en nosotros.

9 Si confesamos nuestros pecados, él es fiel y justo para que nos perdone nuestros pecados, y nos limpie de toda maldad.

10 Si dijéremos que no hemos pecado, lo hacemos á él mentiroso, y su palabra no está en nosotros.
