Maybe be an ambulance and fire truck chaser. Maybe provoke some Mt. Carmel confrontations with false prophets and satanic religions. Note that our lesson text addresses other manifestations of faith and power besides great wonders and miracles. We know Stephen best for his bold preaching and martyrdom. Sometimes I think most people either have a spine so flimsy you can't prop them up or else use their solid, rigid backbone to whack others over the head.
Christian boldness knows the truth and stands for it and on it without apology.
Faith takes the witness out in confidence, knowing that the work is the Lord's. I'll trust the Spirit to do the convincing. Faith believes that God will use even the most faltering human words to bring about divine accomplishments in the lives of people. Power makes our witnessing assured and compelling. Power allows the witness to confront all opposition in all realms as he tenaciously strives to wrench men's souls from the claws of the evil one.
