Read: Acts 6:8-15
And Stephen, full of grace and power, was doing great wonders and signs among the people. (Acts 6:8 ESV)
Jesus' followers are supposed to be like Stephen. We are supposed to be people who are full of grace and power. People who do great wonders and signs.
Stephen was so impactful as he ministered in the name of Jesus that it bewildered the extremely religious Jewish leadership. So much so that, just as they had done to Jesus, they decided to have Stephen killed. They concocted a phony trial with false witnesses, and they besmeared his reputation through villainous slander.
Stephen remained full of grace throughout. And it was only by the power of God that he withstood their torments. In fact, the whole ordeal only served to better illuminate the power of God at work in Stephen's life.
Today when Christians talk about God's power they are often looking for something supernatural or miraculous. I believe those things can and do happen, but perhaps more often the power of God works in His followers to sustain them through difficulty. Grace and power are fully at work when a lost sinner is made to shine like a saved saint.
