The light of Christ shines within the heart of every believer,and they desire nothing that is of the darkness. John the baptist was the forerunner of Jesus and he was a burning and shining light. (John 5:32-36). Pauls testimony was that he was to open the eyes of the people to the truth in Christ,and to turn them from darkness to light!(Acts 26:15-18).
Scripture makes a distinct difference how light is of righteousness while darkness is of wickedness and evil (John 3:17-21) 17 For God sent not his Son into the world to condemn the world; but that the world through him might be saved.18 He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God
19 And this is the condemnation, that light is come into the world, and men loved darkness rather than light, because their deeds were evil. 20 For every one that doeth evil hateth the light, neither cometh to the light, lest his deeds should be reproved. 21 But he that doeth truth cometh to the light, that his deeds may be made manifest, that they are wrought in God.
Those who serve Christ are known as the children of light,and are the light of the world ( Ephesians 5:8-17),(Matthew 5:14-16).
For anyone who thinks the darkness is as a cover for their evil deeds,and that their works will be hid from the eyes of God would be surprised to know the darkness and light are both alike to Him!(Psalm 139:7-12). 7 Whither shall I go from thy spirit? or whither shall I flee from thy presence? 8 If I ascend up into heaven, thou art there: if I make my bed in hell, behold, thou art there. 9 If I take the wings of the morning, and dwell in the uttermost parts of the sea; 10 Even there shall thy hand lead me, and thy right hand shall hold me. 11 If I say, Surely the darkness shall cover me; even the night shall be light about me. 12 Yea, the darkness hideth not from thee; but the night shineth as the day: the darkness and the light are both alike to thee.
LIGHT……. John 1:1-9
DARK …… Job 24:13-17
