1 John 1:5 This then is the message which we have heard of him, and declare unto you, that God is light, and in him is no darkness at all.
Who doesn’t like a bright sunny day, but for those whose mind is set on doing no good the darkness of the night is preferred. In fact the light is used to mark out houses to rob when the night falls (Job 24:12-17). They are of those that rebel against the light; they know not the ways thereof, nor abide in the paths thereof. The murderer rising with the light killeth the poor and needy, and in the night is as a thief. The eye also of the adulterer waiteth for the twilight, saying, No eye shall see me: and disguiseth his face. In the dark they dig through houses, which they had marked for themselves in the daytime: they know not the light. For the morning is to them even as the shadow of death: if one know them, they are in the terrors of the shadow of death.
Our Lord is the light of the world, for man loved darkness and not light because their deeds were evil. For those who love the Lord and do stand for what is right His light and truth is well accepted (John 3:17-21), For God sent not his Son into the world to condemn the world; but that the world through him might be saved. 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. And this is the condemnation, that light is come into the world, and men loved darkness rather than light, because their deeds were evil. For every one that doeth evil hateth the light, neither cometh to the light, lest his deeds should be reproved. But he that doeth truth cometh to the light, that his deeds may be made manifest, that they are wrought in God. (John 1:1-13).
Those who follow Christ are as a candle that shines in a dark place, we are not to hide the truth of the gospel but share it with as many who are searching for answers in life which scripture provides(Luke 11:33-36). No man, when he hath lighted a candle, putteth it in a secret place, neither under a bushel, but on a candlestick, that they which come in may see the light. The light of the body is the eye: therefore when thine eye is single, thy whole body also is full of light; but when thine eye is evil, thy body also is full of darkness. Take heed therefore that the light which is in thee be not darkness. If thy whole body therefore be full of light, having no part dark, the whole shall be full of light, as when the bright shining of a candle doth give thee light.
