Stephen is captured and called to testify before the Sanhedrin, preaching to them that God’s presence isn’t now or ever has been limited to any particular place. He proves it with Abraham, Joseph, Moses, David, and Solomon. But like their forefathers before them, this council failed to respond in faith to God’s gracious invitation. Stephen angered them with his preaching that the law and the temple point to Jesus.
The God of Israel isn't limited to their specific geographical spot in Jerusalem; He is the God of the whole world.
Even with his last breaths, Stephen wasn’t thinking about himself. Like Jesus, he was more concerned with the eternity of those persecuting him because he knew his eternity was secure.
Those who have been redeemed by Jesus, the Righteous One, rest in the Holy Spirit. As the only Righteous One, Jesus bears the iniquity (sin) of God’s people.
