“…to open their eyes, so that they may turn from darkness to light and from the power of Satan to God, that they may receive forgiveness of sins …” (v18). Paul told King Agrippa the whole story of how Jesus appeared to him and gave him a new purpose in life. He was clear that his mission was to urge people to repent and trust in the Savior, and he could fulfill that mission anywhere – in the public square, in a synagogue, in a prison, or courtroom.
“So I stand here testifying …” (v22). When we are secure in our identity and purpose, like Paul, every place is a place to know Christ and to make him known.
