But you will receive power when the Holy Spirit comes on you; and you will be my witnesses in Jerusalem, and in all Judea and Samaria, and to the ends of the earth. Acts 1:8
These parting words from Jesus, just before His ascension reiterate both the call of all followers of Jesus and the promise of the Holy Spirit to empower that call. It is a fuller description than what Luke writes in his gospel (You are witnesses of these things. 49 I am going to send you what my Father has promised; but stay in the city until you have been clothed with power from on high.”
Matthew’s gospel gives us the Great Commission – to go out into all the world teaching about Jesus, and again promises an eternal presence.
As followers of Christ, we all have the call to bear witness to Jesus in many aspects of our lives. Some preach, some teach, some can simply talk about Jesus. We all have a story to tell, and we are all called to share that story. Fortunately, we need not fear doing this for God will empower us in our ministries, and God will be with us. Always.
