How do we know that Christ is the Holy One of God?

In Luke 4:34, an unclean spirit acknowledges Jesus, saying, 'I know thee who thou art, the Holy One of God.' This declaration aligns with the truth of Christ's sinlessness, as recorded in Hebrews 4:15, where it says that Jesus was tempted in all points like we are, yet without sin. His life and actions, fully embodying holiness, set Him apart as the Savior who bears the sins of humanity. The acknowledgment from spiritual forces illustrates His divine identity and authority, confirming that He is indeed the Holy One sent to redeem His people.
