We know Jesus is the true Christ through his miraculous works and fulfillment of scripture.
Throughout the Gospel of John, Jesus points to his miracles as evidence of his divine mission and identity. In John 7:31, many people believed in him because of the great works he performed, suggesting that they realized he fulfilled the scriptural promises about the Messiah. The miracles were not just signs; they were intended to lead people to trust in him and recognize him as the one who was sent by the Father (John 5:36). Additionally, the scriptures foretold that the Messiah would perform miraculous signs, such as healing the sick and raising the dead, which Jesus accomplished during his earthly ministry. Thus, belief in his identity is anchored in both the miraculous acts he performed and the prophetic declarations found in the Old Testament.
