How do we know Jesus is the Holy One of Israel?

The identity of Jesus as the Holy One of Israel is affirmed throughout both Testaments. Isaiah highlights the Holy One as our Maker (Isaiah 30:15) and emphasizes His role in salvation and redemption (Isaiah 43). In the New Testament, His recognition as the Holy One is echoed by a demon in Mark 1:24, proclaiming, 'Thou Jesus of Nazareth, art thou come to destroy us? I know thee who thou art, the Holy One of God.' This cohesive scriptural testimony across generations confirms Jesus as the one who fulfills the prophecies concerning the Messiah, showcasing His divine nature and redemptive work.
