"Jesus quoted Psalm 22:1 on the Cross because, first, it suited His emotions while receiving His Fathers wrath instead of His favor. But more importantly, Jesus quoted the first verse of Psalm 22 in order to help onlookers (perhaps more so, readers of the Gospel) understand that what was happening to Jesus was fulfilling what the Scriptures had prophesied about the Messianic King, as seen in the whole of the victorious Psalm 22."
