Positive Impact

Matthew 5:13-16

“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.”

Christians are called by God to make a positive impact on the world.

The Character of the Christian

As Christians, we are called to be salt. That means we should have a preserving, penetrating, and purifying impact on the world. Just as salt wards of rot and decay when rubbed into meat, Christians should act to ward off further decay in the world through prayer and pursuing righteousness.

Salt also has a penetrating ability. It will penetrate and infiltrate whatever it touches. Christians have been called to be an active force in the world around us. The Church should be a militant army, charging the very gates of hell (Matt. 16:18).

Finally, salt has a cleansing ability. Salt can clean an open wound. Often the very presence of a Christian can have a purifying effect on the people around him or her. Don’t be offended if the conversation quickly changes when you walk up to a group of people. Instead, thank God that He has allowed you to have a purifying effect in the world.

The Commission of the Christian

As Christians, we are also to be light. This means that wherever we go, we drive back the darkness. By its nature, light always defeats darkness. You can be in the darkest place imaginable and even the smallest match, when lit, has the power to drive away that black, oppressive darkness. Christians are to be beacons of truth.

Light also changes dreariness. Even the most dreary of days can be instantly transformed by light cutting through the clouds. Christians should have the same kind of effect on people. We ought to brighten people’s lives.

Furthermore, light does not exist to call attention to itself, rather call attention to that which it illuminates. Our Christian witness should aim to shine light on Christ rather than ourselves.


It is the Christian’s responsibility to be salt and light in the world. We are to have a preserving effect, a penetrating effect, and purifying effect on the world. We are also to push back the darkness, brighten others’ lives, and illuminate the gospel over ourselves. Consider this day whether you are living in such a way. Does your life look any different than those who we have been called to live as a witness to? If it does, then do not weary in doing good. Continue being salt and light to those around you. If it does not, repent and ask God to make you salty again, cause your light to shine brighter than ever.
