As Christians we are to be salt and light in the world.
Matthew 5:13-16 New International Version (NIV)
13 “You are the salt of the earth. But if the salt loses its saltiness, how can it be made salty again? It is no longer good for anything, except to be thrown out and trampled underfoot.
14 “You are the light of the world. A town built on a hill cannot be hidden. 15 Neither do people light a lamp and put it under a bowl. Instead they put it on its stand, and it gives light to everyone in the house. 16 In the same way, let your light shine before others, that they may see your good deeds and glorify your Father in heaven.
Christians are not to blend in with the society and culture. When Christians do this they become diluted. Your value becomes decreased. Your worth is decreased. You become useless to God because you have compromised your witnessing abilities. There can be no compromising of the gospel if we want the full effect. The gospel is medicine for a sin sick world. The gospel is needed. The world needs the gospel. Spread the gospel. Spread the good news. Jesus is the medicine that is needed for all our hurts and pains.
