Acts 4:19-20 But Peter and John replied, "Do you think God wants us to obey you rather than him? we cannot stop telling about everything we have seen and heard."
We have to be this strong, as strong as Peter and John! If we can't do it with the people we know, how will we ever be able to do it with authority if it becomes necessary in our lives.
We didn't walk with Jesus and see his work up close. But if we walk with Jesus in our lives today, we can see His work in our lives and the lives of the people around us. It is up to us to tell those stories! To make God known and real to the people we come in contact with.
We have to learn to tell people where our hope comes from, where our love comes from, where our joy comes from. When people don't know God they assume it comes from the "things" we have that they don't have. If we make more money they thin that is our joy. If we have a sweeter family they think that is our joy. If we stay home when they work they think that is our joy. The only way they can understand that God is our joy, peace, comfort is of we tell our story, even when people tell us not to.
