Luke 23: the temptation when the Messiah was crucified

Jesus made many miracles. When Jesus restored the vision of the blind (among many other miracles), he was restoring people. These miracles showed the love of the Lord for the poor and sick. Jesus also pointed to the prophet Isaiah and Daniel (among others) - he was the one who was fulfilling the prophecies. Despite his words and signs, Jesus was mocked as if he was a crazy man claiming to be the Messiah when in fact, Jesus was very clever not to draw much attention about it.
We read:

36-37 The soldiers also came up and poked fun at him, making a game of it. They toasted him with sour wine: “So you’re King of the Jews! Save yourself!”

38 Printed over him was a sign: this is the king of the Jews.

39 One of the criminals hanging alongside cursed him: “Some Messiah you are! Save yourself! Save us!”

There are many ways that we may understand salvation. Salvation from what? From the death? From the sins? From the Romans? When they said: "Save yourself" is something like "perform a miracle to save from your own death". When the criminals said "Save us", it is the same. Save us from our deaths.
It was a temptation: Jesus was going to be saved, but by trusting on the Father; not by himself.
It is the same temptation that we have: we are to be saved by Jesus, not by ourselves.
