Then spake Jesus again unto them, saying, I am the light of the world: he that followeth me shall not walk in darkness, but shall have the light of life.(John 8:12)
By following Him we too are known as the light of the world! By His holy spirit He still walks the earth through all who do His will (Matthew 5:14-16) Ye are the light of the world. A city that is set on an hill cannot be hid. Neither do men light a candle, and put it under a bushel, but on a candlestick; and it giveth light unto all that are in the house. Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven.
As christians we are instructed not to go in the way of evil men, and by doing so our path will be as a shining light! (Proverbs 4:14-18) Enter not into the path of the wicked, and go not in the way of evil men. Avoid it, pass not by it, turn from it, and pass away. For they sleep not, except they have done mischief; and their sleep is taken away, unless they cause some to fall. For they eat the bread of wickedness, and drink the wine of violence. But the path of the just is as the shining light, that shineth more and more unto the perfect day. (Isaiah 42:16).
Many know the words of the 23rd Psalm, and within it we read “Yea, though I walk through the valley of the shadow of death, I will fear no evil: for thou art with me; thy rod and thy staff they comfort me”. This life we pass through is the shadow of death and the Lord is the light which shines and gets us through. (Isaiah 9:2) The people that walked in darkness have seen a great light: they that dwell in the land of the shadow of death, upon them hath the light shined.
When this world passes away and our Lord returns we will then inhabit an eternal world where only righteousness will dwell, a place with walls called salvation and gates named praise! A land where there will be no need of the sun or moon, for the Lord will be it’s everlasting light! (Isaiah 60:18-22) Violence shall no more be heard in thy land, wasting nor destruction within thy borders; but thou shalt call thy walls Salvation, and thy gates Praise. The sun shall be no more thy light by day; neither for brightness shall the moon give light unto thee: but the LORD shall be unto thee an everlasting light, and thy God thy glory. Thy sun shall no more go down; neither shall thy moon withdraw itself: for the LORD shall be thine everlasting light, and the days of thy mourning shall be ended. Thy people also shall be all righteous: they shall inherit the land for ever, the branch of my planting, the work of my hands, that I may be glorified. A little one shall become a thousand, and a small one a strong nation: I the LORD will hasten it in his time. (Rev 21:22-27).
