Luke 13:21

18 He said therefore, Unto what is the kingdom of God like? and whereunto shall I liken it?

19 It is like unto a grain of mustard seed, which a man took, and cast into his own garden; and it grew, and became a tree; and the birds of the heaven lodged in the branches thereof.

20 And again he said, Whereunto shall I liken the kingdom of God?

21 It is like unto leaven, which a woman took and hid in three measures of meal, till it was all leavened.

22 And he went on his way through cities and villages, teaching, and journeying on unto Jerusalem.

23 And one said unto him, Lord, are they few that are saved? And he said unto them,

24 Strive to enter in by the narrow door: for many, I say unto you, shall seek to enter in, and shall not be able.
