The rest of the story from Acts 1:8 explains that Christ-followers have a mission while here on earth. They are to be Christ’s witnesses all over this planet. It’s as if Christ said, “Think you’re missing the book smarts, the street smarts, the looks, the talent, or the speaking ability to accomplish this mission? Don’t be concerned with those things, because you have my mountain-moving, life-transforming, death-defying power on your side.”
