We know Christ is the Messiah through prophecies fulfilled and His works, including His miracles, as stated in the Scriptures.
The fulfillment of Old Testament prophecies establishes Christ as the Messiah. For instance, Genesis 49:10 foretells the coming of Shiloh, to whom the scepter was to be given, which corresponds to Christ’s life and ministry. Additionally, passages like Malachi 4:5 speak of the coming of Elijah, fulfilled in John the Baptist, preparing the way for the Lord. Throughout Scripture, we see the evidence of Christ fulfilling various prophecies and miracles that attest to His identity as the Messiah. John 3:2 records that Nicodemus recognized Jesus as a teacher from God based on His miracles. This thorough pattern of divine proclamation and fulfillment provides evidence that Christ indeed is the promised Savior.
