Jesus said, "I am the Light of the World. He who follows Me shall not walk in darkness, but have the light of life." John 8:12
My pastor preaches often that "darkness" in the Bible refers to ignorance of truth. This explains hard-working devoted church folks who seemed defeated and never demonstrate the joy, peace and abundant life displayed in the first church in the New Testament.
Paul speaks of God working through us in Philippians 2....v.15 "you shine as lights in the world." God has blessed me with peace and joy no matter what is surrounding me or "biting at my ankles" or "hammering at my thoughts" that I believe He shines His light through me wherever I am. When I enter a "dark" place I expect the atmosphere to change because of Christ in me.
Thrive Christians blog is lighting up!!! I'm not sure how sophisticated a "light" I am in the Kingdom of God. I suspect I might be no more than a little birthday candle: just a tiny cheap squirt of wax covering a short burning wick. Oh, I'll joyfully be God's birthday candle of light. I love seeing faces in a darkened room when lit candles on a birthday cake come forth with "ooh's" and "ah's" and then "Happy Birthday to you..."
Life! Let's celebrate life; and all that it gives us in delights and challenges.
