What does Luke 17 5-10 mean?

Answer 1

It means that nothing is impossible to God. He doesn't want from us big things. If we could only have a little faith - that's is fine. So, we should ask ourselfs how many faith we've got.

Also this fragment say about not being too proud because we do and choose good things. That's something normal for christians to choose good things, that's our duty.

Luke 17:5-10

The apostles said to the Lord, "Increase our faith!" So the Lord replied, "If you had faith the size of a Mustard Seed, you could say to this black mulberry tree, 'Be pulled out by the roots and planted in the sea,' and it would obey you.

"Would any one of you say to your slave who comes in from the field after plowing or shepherding sheep, 'Come at once and sit down for a meal'? Won't the master instead say to him, 'Get my dinner ready, and make yourself ready to serve me while I eat and drink. Then you may eat and drink'? He won't thank the slave because he did what he was told, will he? So you too, when you have done everything you were commanded to do, should say, 'We are slaves undeserving of special praise; we have only done what was our duty.'"
