"Is not the point of this parable [Luke 14:16–24] that the invitation to God's kingdom is sent out through his servant to all indiscriminately? 'Go out to the highways and hedges, and compel people to come in!' Until Jesus comes back, we may assume that the banquet hall is not full. But God aims to fill it. So the charge lies upon the church even now to go out, without any favoritism to race or color or class or creed, and 'compel' them to come in—that is, to be urgent in our invitations and persuasions." - John Piper
