The sermon “Salt and Light” draws from the Gospel of Matthew, specifically verses 13-16, to encourage followers to be beacons of positive influence in the world. It uses the imagery of salt and light to emphasize the impact that believers can have on society, highlighting the importance of their actions in shining a light on God’s glory and inspiring others to do the same. The sermon stresses that Christians are called to be agents of change, not hidden away, but actively demonstrating their faith through good works that inspire others.
