God revealed His purpose for describing a future temple to Ezekiel (referred to here as “Son of man”). Ezekiel’s temple has never been built. Solomon built the first, which was destroyed by the Babylonians, as Ezekiel’s prophecy predicted. Zerubbabel built the second, which was super-sized by Herod the Great, but destroyed by the Romans in 70 AD. Ezekiel’s temple is sometimes called the “Third Temple,” or the “Millennial Temple.” Depending on one’s eschatology, some would see it as describing a spiritual temple fulfilled by the church. Others would see a literal fulfillment in the last days or during the Millennial kingdom. Regardless, Ezekiel was to describe it, so that the people of Israel would be “ashamed of all their sins.”
Shame is an appropriate response to sin. Yet, there is a hardening of the heart which reduces shame to a dull tickling and then a complete denial. Ezekiel was to describe God’s future temple and returning glory, so that their hearts would feel shame, turning to God in repentance for forgiveness and salvation.
Christ is God’s provision for our sin and shame. He came to take the sin and shame of those would believe in Him.
