1 That which was from the beginning, that which we have heard, which we have seen with our eyes; that which we contemplated, and our hands handled, concerning the word of life; 2 (and the life has been manifested, and we have seen, and bear witness, and report to you the eternal life, which was with the Father, and has been manifested to us:) 3 that which we have seen and heard we report to you, that ye also may have fellowship with us; and our fellowship is indeed with the Father, and with his Son Jesus Christ. 4 And these things write we to you that your joy may be full.

5 And this is the message which we have heard from him, and declare 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 darkness, we lie, and do not practise 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 our sins, and cleanse us from all unrighteousness. 10 If we say that we have not sinned, we make him a liar, and his word is not in us.

1 Mis algusest peale on olnud, mida me oleme kuulnud ja oma silmaga näinud, mida oleme vaadanud ja oma käega puudutanud – seda me kuulutame Elu Sõnast. 2 See Elu sai avalikuks; me oleme ise näinud ning tunnistame ja kuulutame teile igavest elu, mis oli Isa juures ja on ilmutatud meile – 3 seda me oleme näinud ja kuulnud, ja kuulutame ka teile, et teilgi oleks osadus meiega. Meil on osadus Isaga ja tema Poja Jeesuse Kristusega. 4 Ja me kirjutame seda, et meie rõõm oleks täielik.

5 See on sõnum, mida oleme kuulnud temalt ja kuulutame teile: Jumal on valgus ja temas ei ole mingit pimedust. 6 Kui väidame, et meil on osadus temaga, aga käime pimeduses, siis me valetame ega tee tõtt. 7 Aga kui me käime valguses, nagu tema on valguses, siis on meil osadus üksteisega ning tema Poja Jeesuse veri puhastab meid igast patust.

8 Kui me väidame, et meil ei ole pattu, siis me petame iseennast, ning tõde ei ole meie sees. 9 Kui me oma patud tunnistame, on tema ustav ja õige, nii et ta annab andeks meile meie patud ja puhastab meid kõigest ülekohtust. 10 Kui väidame, et meie ei ole pattu teinud, siis teeme tema valelikuks ja tema sõna pole meis.
