Luke 13:18-21 and Romans 8:18-25

Luke 13:18-21
18 And so he said: "To what is the kingdom of God similar, and to what figure shall I compare it?
19 It is like a grain of mustard seed, which a man took and cast into his garden. And it grew, and it became a great tree, and the birds of the air rested in its branches."
20 And again, he said: "To what figure shall I compare the kingdom of God?
21 It is like leaven, which a woman took and hid in three measures of fine wheat flour, until it was entirely leavened."
22 And he was traveling through the cities and towns, teaching and making his way to Jerusalem.
23 And someone said to him, "Lord, are they few who are saved?" But he said to them:
24 "Strive to enter through the narrow gate. For many, I tell you, will seek to enter and not be able.
25 Then, when the father of the family will have entered and shut the door, you will begin to stand outside and to knock at the door, saying, 'Lord, open to us.' And in response, he will say to you, 'I do not know where you are from.'

Romans 8:18-25
18 For I consider that the sufferings of this time are not worthy to be compared with that future glory which shall be revealed in us.
19 For the anticipation of the creature anticipates the revelation of the sons of God.
20 For the creature was made subject to emptiness, not willingly, but for the sake of the One who made it subject, unto hope.
21 For the creature itself shall also be delivered from the servitude of corruption, into the liberty of the glory of the sons of God.
22 For we know that every creature groans inwardly, as if giving birth, even until now;
23 and not only these, but also ourselves, since we hold the first-fruits of the Spirit. For we also groan within ourselves, anticipating our adoption as the sons of God, and the redemption of our body.
24 For we have been saved by hope. But a hope which is seen is not hope. For when a man sees something, why would he hope?
25 But since we hope for what we do not see, we wait with patience.
