Matthew 16:18 And I tell you, you are Peter, and on this rock I will build my church, and the gates of hell shall not prevail against it.
Whether the rock to which Jesus refers is Peter or his profession, it is clear that Jesus is speaking of his church as a future event. The nation of Israel was not the church. Although there was a remnant saved during the old covenant era, the church of Jesus Christ began at Pentecost.
