Jesus' work didn't end at the cross. It continues because Jesus lives. He reminds His disciples in John 16 that He will see them again. We serve a risen Savior.
King Saul had the Spirit of God upon him at the beginning of his reign. And it made all the difference. We must have spiritual power in our lives.
God sends His people into the world to bear fruit for His glory. But the world doesn't want us. Let's continue to be about the Father's business in this world.
