As Christians we are given to the world as salt and light. Our lives and our faith are to be lived in the open. As the saying goes, we should be open books - accessible and with nothing to hide. When the world looks at our lives the only offense they should see is the offense of the Gospel. The only crime of which we could be convicted should be that of preaching Jesus Christ, crucified and resurrected, assuming that ever becomes a crime. And even that "crime" is one of which we should not be ashamed, but be willing to commit openly.
We must beware of our tendency to create sub-cultures which hide us from the world and put our light under a bushel. We must abandon any practice, besides the affirmation and preaching of the gospel, which puts us in violation of the laws of our government. (See Rom. 13.) All our behavior, public and private, should be above reproach and such that if exposed openly the cause of Christ would not be brought into disrepute. We must be willing to forgo even our rights, if it becomes necessary, for the sake of the Gospel. (See 1 Cor. 9) We must never let our politics, or our lifestyle preferences become a barrier between the light of our Gospel and the world so steeped in darkness.
“You are the salt of the earth, but if salt has lost its taste, how shall its saltiness be restored? It is no longer good for anything except to be thrown out and trampled under people's feet.
You are the light of the world. A city set on a hill cannot be hidden. Nor do people light a lamp and put it under a basket, but on a stand, and it gives light to all in the house. In the same way, let your light shine before others, so that they may see your good works and give glory to your Father who is in heaven." Matthew 5:13-16
