In Paul's parable of the Two Olive Trees in
Romans 11:15-27,
he shows how the natural branches of the Good Olive Tree, [Israel] were broken off because of unbelief,
that the Wild Olive Tree of the Church might be grafted in, which because of unbelief, would be displaced that the natural branches might be grafted back again,
showing us that the Church does not take the place of Israel permanently, but simply fills up the gap between Israel's casting off and restoration.
