Proverbs 4:18 But the path of the just is as the shining light, that shineth more and more unto the perfect day.
19 The way of the wicked is as darkness: they know not at what they stumble.
Verse 18 looks on the opposite of what we just seen but it helps us to see that as we stay true to the wisdom of God we can be a shinning light to lost world until the time when we are in a perfect world. That world would be eternity in heaven with our Lord and Savior. Verse 19 goes back to the wicked and shows us that evil works in darkness. When there is darkness we know we stumble over things we cannot see and it is the same with people who are wicked. They can not find the right paths to walk in because of the darkness they operate in. We read in John, the Light shineth in darkness and the darkness comprehended it not. Nothing good ever comes from living in darkness we always need to let our light be shinning.
