Jesus in Luke 13:23 NIV urges us to make every effort to enter the narrow gate leading to the Kingdom of Heaven. People from east, west, north, south will take their places at the feast in the Kingdom of God in vs 29. No evildoers can enter-Luke 13:25-28.
Luke 13:18-19 Be a mustard seed, my friend. From a small seed to a big tree. The Kingdom of God is like a small mustard seed.
Luke 13:18-30
[18]Jesus asked, “What is the Kingdom of God like? What shall I compare it with?
[19]It is like this. A man takes a mustard seed and sows it in his field. The plant grows and becomes a tree, and the birds make their nests in its branches.”
[20]Again Jesus asked, “What shall I compare the Kingdom of God with?
[21]It is like this. A woman takes some yeast and mixes it with forty litres of flour until the whole batch of dough rises.”
[22]Jesus went through towns and villages, teaching the people and making his way towards Jerusalem.
[23]Someone asked him, “Sir, will just a few people be saved?”Jesus answered them,
[24]“Do your best to go in through the narrow door; because many people will surely try to go in but will not be able.
[25]The master of the house will get up and close the door; then when you stand outside and begin to knock on the door and say, ‘Open the door for us, sir!’ he will answer you, ‘I don’t know where you come from!’
[26]Then you will answer, ‘We ate and drank with you; you taught in our town!’
[27]But he will say again, ‘I don’t know where you come from. Get away from me, all you wicked people!’
[28]How you will cry and grind your teeth when you see Abraham, Isaac, and Jacob, and all the prophets in the Kingdom of God, while you are thrown out!
[29]People will come from the east and the west, from the north and the south, and sit down at the feast in the Kingdom of God.
[30]Then those who are now last will be first, and those who are now first will be last.”
