Jonah 3:1-10; Psalm 50(51):3-4,12-13,18-19; Luke 11:29-32
Luke uses Jonah as a sign, or pre-figuring, of the way in which Jesus would bring salvation to the world. Not as a warrior - saviour, but as a quiet, suffering but irresistible force.
Jonah was tasked by God to go and save a sinful nation, but refused, perhaps believing himself to be unworthy. When God did convert them, Jonah was not happy, because they were not Jews - they were the other, not us. Jesus was crucified because he also was a sign of contradiction, and this riled against the hearts of many. The contrast between the unwilling but successful servant of God, and the willing but (in human terms) failure that was Jesus.
Solomon was thought to be the seat of all wisdom - even the heathen queen of the south came to hear him - and in another balance, Jesus is shown out as a fool. The author Luke is using these balances of opposites to emphasise the important difference between all those that went before, and the one true saviour, Jesus.
Jesus overturns all this - by rising from the dead he lifts us all out of the traps we have set for ourselves by relying on ancient wisdoms and ancient sets of values. We do not have to be wise, nor do we have to be strong.
We just need to accept that Christ has saved us.
