Will he live up to his name?

Today I read the account in Luke's Gospel of the crucifixion of Jesus:

³⁵And the people stood by, watching, but the rulers scoffed at him, saying, "He saved others; let him save himself, if he is the Christ of God, his Chosen One!" ³⁶The soldiers also mocked him, coming up and offering him sour wine ³⁷and saying, "If you are the King of the Jews, save yourself!" ³⁸ There was also an inscription over him, "This is the King of the Jews."

³⁹One of the criminals who were hanged railed at him, saying, "Are you not the Christ? Save yourself and us!" ⁴⁰But the other rebuked him, saying, "Do you not fear God, since you are under the same sentence of condemnation? ⁴¹And we indeed justly, for we are receiving the due reward of our deeds; but this man has done nothing wrong."⁴²And he said, "Jesus, remember me when you come into your kingdom." ⁴³And he said to him, "Truly, I say to you, today you will be with me in Paradise."

This repeating question about whether Jesus can save brings to mind the beginning of Luke's Gospel where the angel Gabriel spoke to Mary. (Note that Jesus is the greek form of Joshua which means "the LORD saves"):

you will conceive in your womb and bear a son, and you shall call his name Jesus. ³²He will be great and will be called the Son of the Most High. And the Lord God will give to him the throne of his father David, ³³and he will reign over the house of Jacob forever, and of his kingdom there will be no end."
