But if we are walking in the light, as he is in the light, we are all united with one another, and the blood of Jesus his Son makes us clean from all sin.

εαν ομως περιπατωμεν εν τω φωτι, καθως αυτος ειναι εν τω φωτι, εχομεν κοινωνιαν μετ' αλληλων, και το αιμα του Ιησου Χριστου του Υιου αυτου καθαριζει ημας απο πασης αμαρτιας.

But if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin.
