2.29- Earthly temples can be descrated and destroyed, spiritual houses of worship cannot.

2.29-

Men will destroy and mock physical places of religion when by those who win the physical battles.  Jesus took a different approach toward His enemies.  Overcome evil with Good..

Physical cities and nations that can be seen can be destroyed. 

Jesus taught that the place of worship of God is in the location of Spirit and truth.  (John 4.24)
Jesus taught that the kingdom of God is within you.
One of the followers of Jesus, Paul, said that the temple of God is the church, God's people, and that in fact our bodies are a temple of God who be kept holy and pure and healthy.

Mark 13.
¹⁴ “But when you see the abomination of desolation standing where it should not be (let the reader understand), then those who are in Judea must flee to the mountains. ¹⁵ The one who is on the housetop must not go down, or go in to get anything out of his house; ¹⁶ and the one who is in the field must not turn back to get his coat. ¹⁷ But woe to those who are pregnant and to those who are nursing babies in those days! ¹⁸ But pray that it may not happen in the winter. ¹⁹ For those days will be a time of tribulation such as has not occurred since the beginning of the creation which God created until now, and never will. ²⁰ Unless the Lord had shortened those days, no ^[i]life would have been saved; but for the sake of the ^[j]elect, whom He chose, He shortened the days. ²¹ And then if anyone says to you, ‘Behold, here is ^[k]the Christ’; or, ‘Behold, He is there’; do not believe him; ²² for false Christs and false prophets will arise, and will show ^[l]signs and wonders, in order to lead astray, if possible, the elect. ²³ But take heed; behold, I have told you everything in advance.

Daniel 9.
²⁷ And he will make a firm covenant with the many for one week, but in the middle of the week he will put a stop to sacrifice and grain offering; and on the wing of ^[ae]abominations will come one who ^[af]makes desolate, even until a complete destruction, one that is decreed, is poured out on the one who ^[ag]makes desolate.”
