Ye are the light of the world a city that is set on a hill cannot be hid. Let your light so shine before men that they may see your good works, and glorify your father which is in heaven. the purpose of a lighthouse is to serve as a navigational aid and to warn boats of dangerous areas. The light that's in us is to be seen by those that are in darkness.
Beloved let us love one another for love is of God and every one that loveth is born of God , and knoweth God. He that loveth not knoweth not God. For God is love. So when you say I can love you from a distance thats not the love of God or I love you but i don't like you, that's not the love of God. Jesus said This is my commandment that you love one another as i have love you.
