Stephen was brought before the sanhedrin because he preached the gospel in the temple. They said explain yourself. Stephen began with Abraham and explained the promise of God. He show how they hadn’t recieve the promise but Abraham obeyed God. And it wasn’t until Moses did they receive the promise from God. He showed how Jesus was the promise from God. And they refused to accept and killed Jesus. When Stephen said this, they were all pierced in their hearts. They took him outside the city and stoned him to death. Stephen looked up as he was dying and received the promise of God. This earth isn’t our promise. Heaven is our destination. That is the promise. It is the promise given to Adam, Abraham, Moses and David. We only walk through this world on our way home. The promise of God is Jesus.
