How do we know that Christ is the fulfillment of the temple?

Christ is the fulfillment of the temple as He embodies the presence of God among His people, rendering the physical temple obsolete. In the Old Testament, the temple served as a tangible representation of where God met His people. However, in the New Testament, with Christ's coming, He became the living temple, as seen in John 2:19-21, where Jesus refers to His body as the temple that will be raised in three days. This indicates that through His life, death, and resurrection, Christ has established a new and everlasting covenant with His people, making them the temple of God. This also aligns with the vision in Revelation 21:3, where it proclaims that God dwells among His people, assuring that the ultimate fulfillment of the temple is found in the person of Jesus Christ, who is both Lord and Savior, thus establishing a permanent connection between God and humanity.
