In the first Christian sermon, Peter established that Jesus the man is the Savior we need. He didn’t stop there, though. He went on to proclaim the powerful reality that Jesus is the King we need as well. He came in the line of David, anticipated by David’s own Psalms, and Jesus is the ultimate King that was promised to David. The implications for us are massive, not only individually, but on the whole of how God’s people think about the role we play in this world corporately.
