In the first book, Theophilus, I wrote about all that Jesus did and taught from the beginning until the day when he was taken up to heaven, after giving instructions through the Holy Spirit to the apostles whom he had chosen. After his suffering he presented himself alive to them by many convincing proofs, appearing to them during forty days and speaking about the kingdom of God. While staying with them, he ordered them not to leave Jerusalem, but to wait there for the promise of the Father. “This,” he said, “is what you have heard from me; for John baptized with water, but you will be baptized with the Holy Spirit not many days from now.” So when they had come together, they asked him, “Lord, is this the time when you will restore the kingdom to Israel?” He replied, “It is not for you to know the times or periods that the Father has set by his own authority. But you will receive power when the Holy Spirit has come upon you; and you will be my witnesses in Jerusalem, in all Judea and Samaria, and to the ends of the earth.” (Acts 1:1-8, NRSV)
Jesus was dead, but then He rose and presented Himself in many ways over 40 days.
And He told His disciples to wait for the Holy Spirit, who would empower them to be His witnesses, in Jerusalem, in all Judea and Samaria, and to the ends of the earth!
What does that mean?
Well you can see in the picture Jerusalem, and below and above Judea, and then Samaria, and the on to the rest of the world.
It is like a ripple in the pond when you drop the rock in.
Your actions of showing forth your life in Christ should cause the waters to move in all directions around. You are to take His message of Love. The love that He did on the cross for and send it rippling into the lives of those around you.
So go and be a witness for the grace and mercy of Jesus in all the world!
