the son of Methuselah, the son of Enoch, the son of Jared, the son of Mahalaleel, the son of Cainan,

 God said to him, "You are my beloved Son; with you I am well pleased." That saying is composed of two texts. You are my beloved Son--that is from Psalms 2:7 and was always accepted as a description of the Messianic King. In whom I am well pleased--that is part of Isaiah 42:1 and is from a description of the servant of the Lord whose portrait culminates in the sufferings of Isaiah 53:1-12. Therefore in his baptism Jesus realized, first, that he was the Messiah, God's Anointed King; and, second, that this involved not power and glory, but suffering and a cross. The cross did not come on Jesus unawares; from the first moment of realization he saw it ahead. The baptism shows us Jesus asking for God's approval and receiving the destiny of the cross.
