Jn 2:19-21, Jn 14:27
In the Old Testament, God said that He would give us a more beautiful temple than the beautiful temple in the past and that He would give us peace. (Hag 2:9)
Hag 2:9 The glory of this latter house shall be greater than of the former, saith the Lord of hosts: and in this place will I give peace, saith the Lord of hosts.
Jesus is the true temple that is more beautiful than the Old Testament temple. Jesus said that He, the true temple, would be killed and resurrected on the third day. (John 2:19-21)
John 2:19 Jesus answered and said unto them, Destroy this temple, and in three days I will raise it up. 20 Then said the Jews, Forty and six years was this temple in building, and wilt thou rear it up in three days? 21 But he spake of the temple of his body.
Jesus gives us true peace. (John 14:27)
John 14:27 Peace I leave with you, my peace I give unto you: not as the world giveth, give I unto you. Let not your heart be troubled, neither let it be afraid.
