"You are the light of the world. A town built on a hill cannot be hidden." NIV
"Ye are the light of the world. A city that is set on a hill cannot be hid." KJV
Jesus knew the darkness of the world, that it needed light. If we desire to be like Him, He will give us His light. This light is to be shown by deeds that are pure and consistent with the Christian walk. Through our actions, others will know if we have the light. Our light will expose darkness wherever we are. Those who see the light will glorify God or they will persecute us. It will be just the way it was with the True Light, Jesus.
Heavenly Father, how we thank You that You have made us light in this dark world. We pray that we will walk faithfully so that where we are the darkness will be exposed and the light will overcome all darkness. With You, all this is possible. We pray in Jesus name, Amen.
