Why the different temples?

    Under the law, the temple was in Jerusalem:

Psalm 68:29 Because of thy temple at Jerusalem shall kings bring presents unto thee.

    In the church age, we are the temple:

I Corinthians 6:19 What? know ye not that your body is the temple of the Holy Ghost which is in you, which ye have of God, and ye are not your own?

    In the eternal state, the LORD is the temple:

Revelation  21:23 And I saw no temple therein: for the Lord God Almighty and the Lamb are the temple of it.
