Light

John 1:4
In Him was life, and the life was the light of men.

When Jesus came down to our world, The world that is weighed down with darkness and sin he brought light. His light cast out darkness and sin wherever He was because satan's forces could not withstand Him. If you are a Christian then Gods light is in you. We are called to go and dispel the darkness in this world. Our light should shine so bright that others doing evil would feel uneasy around us. Can you imagine your hangin out with Simon Peter and your brother comes in and yells hey You forgot to take out the trash! Well you wouldn't want to be pushing him out and saying leave me alone I'll do it later because Peter might call down some curse from heaven right?!
Anyway we need to let our lives shine so bright, and have it open to everyone.

The thief does not come except to steal, and to kill, and to destroy. I have come that they may have life, and that they may have it more abundantly. John 10:10
