24 “Strive to enter through the narrow gate, for many, I say to you, will seek to enter and will not be able. 25 When once the Master of the house has risen up and shut the door, and you begin to stand outside and knock at the door, saying, ‘Lord, Lord, open for us,’ and He will answer and say to you, ‘I do not know you, where you are from,’ 26 then you will begin to say, ‘We ate and drank in Your presence, and You taught in our streets.’ 27 But He will say, ‘I tell you I do not know you, where you are from. Depart from Me, all you workers of iniquity.’ 28 There will be weeping and gnashing of teeth, when you see Abraham and Isaac and Jacob and all the prophets in the kingdom of God, and yourselves thrust out. 29 They will come from the east and the west, from the north and the south, and sit down in the kingdom of God. 30 And indeed there are last who will be first, and there are first who will be last.”
