1 Behold, what manner of love the Father hath bestowed upon us, that we should be called the sons of God: therefore the world knoweth us not, because it knew him not. 2 Beloved, now are we the sons of God, and it doth not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is. 3 And every man that hath this hope in him purifieth himself, even as he is pure. 4 Whosoever committeth sin transgresseth also the law: for sin is the transgression of the law. 5 And ye know that he was manifested to take away our sins; and in him is no sin. 6 Whosoever abideth in him sinneth not: whosoever sinneth hath not seen him, neither known him. 7 Little children, let no man deceive you: he that doeth righteousness is righteous, even as he is righteous.
Mwongo ni nani? Ni yule anayekana kwamba Yesu ni Masiha; Mtu wa namna hiyo ni adui wa Kristo, anamkana Baba na Mwana. Maana yeyote anayemkana Mwana, anamkana pia Baba; na yeyote anayemkubali Mwana, anampata Baba pia. Basi, ujumbe ule mliousikia tangu mwanzo na ukae mioyoni mwenu; Kama ujumbe huo mliousikia tangu mwanzo ukikaa ndani yenu, basi, mtaishi daima katika umoja na Mwana na Baba. Na ahadi aliyotuahidia sisi ndiyo hii: uzima wa milele. Nimewaandikieni mambo haya kuhusu wale wanaotaka kuwapotosha ninyi. Lakini, kwa upande wenu ninyi, Kristo aliwamiminieni Roho wake; Na kama akiendelea kukaa ndani yenu, hamhitaji kufundishwa na mtu yeyote; Maana Roho wake anawafundisheni kila kitu na mafundisho yake ni ya kweli, si ya uongo; Basi shikeni mafundisho ya huy o Roho na kubaki katika muungano na Kristo. Naam, watoto, kaeni ndani yake kusudi wakati atakapotokea tuwe hodari bila kuwa na sababu ya kujificha kwa aibu Siku ya kuja kwake.
