Luke 17 explained: Forgiveness, Gratitude, and the Coming Kingdom

Causing others to fall (vv. 1-4)

A millstone was a heavy stone for grinding grain, so Jesus is saying it would be better to drown than to trip up someone vulnerable in their trust in God. He also tells his followers to name wrongs honestly and to forgive each time the person turns back, with 'seven times' most likely meaning without keeping count.

Small faith, ordinary duty (vv. 5-10)

The mustard seed was known for being tiny, so Jesus means even a little real trust in God can do what looks impossible. The servant story adds that obeying God does not put God in your debt, just as a servant then did not expect thanks for doing his ordinary work.

Ten healed, one returns (vv. 11-19)

People with these skin diseases had to live apart, and a priest had to confirm a healing before they could rejoin their community, which is why Jesus sends them off and they are healed on the way. Only one comes back to thank him: a Samaritan, from a neighboring people many Jews of the time saw as outsiders, and Jesus tells him his faith has made him well.

When the kingdom comes (vv. 20-25)

Jesus tells the Pharisees, a strict religious group, that God's kingdom does not arrive with signs you can track, because it is already present; the Greek can mean 'in your midst' or 'within you,' and scholars are unsure which he meant, though many think he points to himself. He then tells his followers that the Son of Man, his usual name for himself, will one day appear as unmistakably as lightning, but first he must suffer and be rejected.

Caught unready, like before (vv. 26-33)

Jesus points to the flood in Noah's time and the fire on the city of Sodom, when people went about everyday life and were caught unprepared. Lot's wife looked back at Sodom as she fled and was turned to salt, so Jesus warns against clinging to possessions and says that grasping at your life is the way to lose it.

One taken, one left (vv. 34-37)

These pictures show the final day dividing people who live and work side by side, though whether 'taken' means swept away in judgment or gathered to safety is debated. The vulture saying seems to be a proverb, but its exact point is unclear; many read it as meaning judgment will come wherever it is deserved, as plainly as birds circling a carcass.

Key verse: Luke 17:21

Where Christians differ

Christians differ on whether Jesus' warnings about the sudden day of the Son of Man point to the Roman destruction of Jerusalem in AD 70, to his own future return, or to both.

Something to think about

When something good happens to you, what makes it easy to move on without going back to say thank you?
