1 John 2:3-11
"Whoever says, 'I am in the light,' while hating a brother or sister, is still in the darkness. Whoever loves a brother or sister lives in the light, and in such a person there is no cause for stumbling. But whoever hates another believer is in the darkness, walks in the darkness, and does not know the way to go, because the darkness has brought on blindness."
This passage from the book of 1 John is about living out our faith. It's about walking the walk as opposed to simply talking the talk. And that's a challenge. Because it's easy to see our faith as simply a way to outline our beliefs and to separate what we think from what others think. But if we only do that, and if we still harbor resentment, anger, and animosity toward others who differ from ourselves, then the scriptures tell us that we have failed to properly understand our faith.
Do we harbor resentment and animosity against others in our lives? Most of us do. The question that this passage prompts us to ask is: 'what are we doing to repair these relationships?' If we answer "nothing," then we are failing to live out our faith. We are failing to walk the walk. Our faith is challenging; it tells us that we cannot be committed to Christ's message which feeling hatred toward others.
