Here are few reasons why Jesus is so angry on the money exchangers and sellers in the temple.

He might see that they don’t have any love for God in what they do.

Also place there occupied  was destined to be place of prayer for pagans/gentiles.

They didn’t let others pray because they were supposed to be more important than gentiles..

We need to look into our lives and check if  temples our our bodies, lives, families, friendships, aren’t  trashed with stuff that takes us away from who we are and who we are meant to be..

John 2:13-25:

Since the Passover of the Jews was near,

Jesus went up to Jerusalem.
He found in the temple area those who sold oxen, sheep, and doves,
as well as the money changers seated there.
He made a whip out of cords
and drove them all out of the temple area, with the sheep and oxen,
and spilled the coins of the money changers
and overturned their tables,
and to those who sold doves he said,
“Take these out of here,
and stop making my Father’s house a marketplace.”
His disciples recalled the words of Scripture,
Zeal for your house will consume me.
At this the Jews answered and said to him,
“What sign can you show us for doing this?”
Jesus answered and said to them,
“Destroy this temple and in three days I will raise it up.”
The Jews said,
“This temple has been under construction for forty-six years,
and you will raise it up in three days?”
But he was speaking about the temple of his body.
Therefore, when he was raised from the dead,
his disciples remembered that he had said this,
and they came to believe the Scripture
and the word Jesus had spoken.John 2:13-25
