Final answer:
Luke's genealogy in the Bible ends with Adam, who is designated as 'the son of God'.
Step-by-step explanation:
Luke's genealogy, as described in the Bible, concludes with the character of God. More specifically, in the Gospel of Luke, the genealogy traces all the way back from Joseph, the husband of Mary, through significant biblical figures, and ultimately ends with "Adam, the son of God" (Luke 3:38). This lineage presents Jesus as descending from the first human, Adam, and therefore connects him to all of humanity, as well as to the divine. This genealogical approach highlights the inclusive and redemptive nature of Jesus' mission in Christian theology.
