Why is Jesus called Jesus?

According to Wikipedia, Yeshua was a common alternative form of the name Joshua in later books of the Hebrew Bible and among Jews of the Second Temple period.

This name corresponds to the Greek spelling Iesous, from which comes the English spelling Jesus.

Yehoshua (Joshua in English) in the Hebrew means "Yahweh is salvation", which is an appropriate name for Jesus the Son of God who, according to the Jesus as recorded in the Gospels, came to seek and save that which was lost.
