Matthew 5.14 says, You are the Light of the world.
People cannot be Drawn Closer to God by you if you do not have the Light to Illuminate them.
If you Draw Near to God and are Controlled Constantly by the Light of God, Spontaneously you will Illuminate the Real Condition of the people who are contacting you.
If we want to Obey the Will of God and Do the Work of God, we Need to be a Light.
