The assurance of Jesus being the true Christ derives from His fulfillment of Old Testament prophecies and His unique nature as both God and man.
The authenticity of Jesus as the true Christ is supported by numerous Old Testament prophecies that predict His coming. For instance, Isaiah 7:14 proclaims that a virgin will conceive and bear a son named Emmanuel, which is fulfilled in the New Testament with the birth of Jesus. Moreover, Christ's identity is further authenticated by His unique nature as the eternal Son of God, who was with God and is God (John 1:1-14). The Scriptures make it clear that denying Jesus' true nature, as both divine and human, is a sign of an antichrist spirit (2 John 1:7). Understanding this is crucial as our faith hinges on recognizing who Christ truly is.
