Jesus begins the Sermon on the Mount by saying that every true subject of His kingdom, that is, every true Christian, is characterized by being poor in spirit. At first glance, it seems that such an interesting expression is an odd way for Jesus to begin a sermon in front of a large crowd. But as we’ll discover together, the starting point for being part of Jesus’ kingdom is to come to Him like a spiritual beggar, depending only on God’s grace for salvation.
