How do we know the church replaces the Old Testament temple?

The transition from the Old Testament temple to the church is established through the completion of the law in Christ. Hebrews 8:13 indicates that the Old Covenant is obsolete, and with Christ's sacrifice, the priestly functions and temple sacrifices became unnecessary. The true temple now reflects the church, composed of believers who worship God directly through Jesus, our High Priest. This dramatic shift signifies the end of the former worship practices and the establishment of a new covenant where the church—as the body of Christ—serves as the dwelling place for God's presence.
