If you had to describe why Jesus came to this earth in a single sentence, what would you say? Would you talk about his teachings? Would you talk about his death? Would you talk about his resurrection?

There is no need to guess or speculate as to why Jesus came - he told us in his own words in Luke 19. In a crazy story about a man named Zacchaeus, Jesus said that he came to "seek and save the lost". What exactly does that mean? And how should/does his mission on this earth inform our mission here on the earth?
