Your light must shine before others, so that they may see your good works. Matthew 5:16
Jesus called us to be salt and the light of the world for his sake. No one lights a lamp and covers it; instead he puts it on a lamp stand, where it gives light to everyone in the house. Jesus calls us to be in the world as salt and light. The church has to be salt and light to the world.
The Church in its totality, must be a city built on a hill; in the last days, the mountain of Yahweh’s house shall be set over the highest mountains and shall tower over the hills Isaiah 2:2, that everybody can see; a dwelling place for truth and fraternity. The Church and all love in the midst of the world is to bring out the essence of a Christian’s identity and the absolute value of the Gospel they share.
Christianity is a light to the world because it is the fullness of the presence of the saving God and his communion and humankind. Every Christian is a Christ on earth, light in the Lord. The light which was given to us and to let it shine through our behavior. Let’s behave as children of light; the fruits of light are kindness, justice and truth in every form. Reject everything which shames us and is done only in the dark for we are now the children of light.
Therefore, children of light must love one another to shine forth our good behavior. In the same way your light must shine before others, so that they will see the good you do and praise your Father in heaven.
People know what you are by what they see, not by what they hear.
