Day 2 Read: 1 John 1:6
If we say we have fellowship with him while we walk in darkness, we lie and do not practice the truth.
Reflect: What inconsistency did John address in verse 6?
Consider: The expression ‘to do the truth’ is found only here in 1 John, but it also occurs in John 3:21 (‘But whoever lives by the truth [lit. ‘does the truth’, poiōn tēn alētheian] comes into the light, so that it may be seen plainly that what he has done has been done through God’). In that context, ‘to do the truth’ is the opposite to ‘doing evil’ (John 3:20), which suggests that here in 1 John ‘doing the truth’ means living in the light of the truth and seeking to avoid sin.
Respond: What does it mean to walk in darkness? How is walking in darkness while also having fellowship with God impossible? What evidence do you see that a large percentage of people in our culture live in darkness and need the light of Jesus? How can you help dispel the darkness in our culture?
