The Bible uses the metaphors of light and darkness a lot. You’ve probably heard about walking in the light, but, if you’re anything like me, you might have had a wrong understanding of what it actually means. You can be doing “good things” and still walking in total darkness, and you can fall short and still be walking in the light. Jesus is the key to walking in the light, not our behavior alone.
People often think that walking in the light means to not sin, and that’s part of it, but walking in the light really just means walking with Jesus. He shows us where we should go and what we should do, but He also exposes our sin. When our sin is exposed, we often choose to walk in darkness in one of two ways: we either try to hide our sin and pretend it never happened or we try to find excuses for why our sin isn’t really that bad (or even go so far as to say that our sin is a good thing). Instead, when we sin (because we will), we should confess our sins to Jesus and He will forgive us and help us to improve.
