Luke chapter 14

10 But when you are invited, take the lowest place, so that when your host comes, he will say to you, 'Friend, move up to a better place.' Then you will be honoured in the presence of all your fellow guests. 

This parable came from the situation Jesus has observed. He taught us that the guests should not decide their position in hierarchy by themselves, but should give the right of dicision to the master. Only has the master the supremacy to judge whether someone deserves to sit at a certain place. In the feast of the end time, that will be the same. It is God who confirms our works and our values but not our own appreciation. So that in our daily life, we should also respect God's evalutation. Do not regard ourselves as hard workers or faithful disciples and suppose ourselves occpying on high ranking positions of salvation list, otherwise we are robbing the supremacy of God and also are losing our humbleness. That might make us fall behind, even fall down from our seat, like these verses said:

For everyone who exalts himself will be humbled, and he who humbles himself will be exalted.(Luke 14.11)

Indeed there are those who are last who will be first, and first who will be last.(Luke 13.30)
