This world is full of evil and ungodliness, which we term DARKNESS. And the opposite of that is LIGHT, which refers to truthfulness and godliness. And the Darkness hides from the Light because the Light exposes it's wrongdoings. Now that is the purpose of believers; to shine our light on the world of darkness and get those living in sin and ungodliness to change their evil ways, to forego the darkness and instead welcome the light of Jesus, which is ever so much more beneficial than the darkness of Satan. Please note too, that as Jesus' ambassadors in this evil world, He is depending on us to accomplish that task. So please, lets' get to it nuh! Much LOVE!
