A few years ago, I preached and led worship at a church in a community near where I live. During the children’s talk I mentioned that Jesus told his disciples that he would be returning to the Father, but that they would receive the Holy Spirit. I compared the Holy Spirit to the batteries in a flashlight.
Light is amazing. Without it, we would not be able to read and discover the world around us. Just like we need physical light to see the world around us, we need spiritual light to see and understand God. Jesus is that spiritual light, and we see in Luke 24:44-53 how he shined a spiritual light on the disciples before his ascension. He helped the disciples to see that shining a light on sin helps those who have lost their way to see him, and he helps us to see the same thing today. He also shined a light on the Old Testament prophecies about his death and resurrection. Luke reminds us that Jesus came to satisfy all of the prophecies made about him in the Old Testament.
