Matthew 5:16

16 You must be sure that your light shines well. Then you will give light to other people. They will see all the good things that you do. Then they will praise God, who is your Father in heaven.’

5:15At this time, people burned oil in a dish to make a light. They called this a lamp. When it was burning, they sometimes put it on a place high on a wall.
5:16Jesus is teaching his disciples about how they must live in a good way that makes God happy. Light shows people the way. In the same way, the disciples must show people the way to God.
