He will oppose and will exalt himself over everything that is called God or is worshiped, so that he sets himself up in God’s temple, proclaiming himself to be God. I don’t know how this can be if the Temple is not rebuilt.
1 Corinthians 6:19-20
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?
20 For ye are bought with a price: therefore glorify God in your body, and in your spirit, which are God's.
John 2:19
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.
Is the temple not already built? If a person takes the mark of the beast isn't the man of lawlessness setting himself up in God’s temple?
Just something to consider.
