Jeremiah 7: the Lord wants a holy people and will destroy the Temple.

 Jeremiah 7 was written before the destruction of the temple. The Lord says that the temple will be destroyed as Shiloh that was in Ephraim was destroyed:

12 “‘Take a trip down to the place that was once in Shiloh, where I met my people in the early days. Take a look at those ruins, what I did to it because of the evil ways of my people Israel.

13-15 “‘So now, because of the way you have lived and failed to listen, even though time and again I took you aside and talked seriously with you, and because you refused to change when I called you to repent, I’m going to do to this Temple, set aside for my worship, this place you think is going to keep you safe no matter what, this place I gave as a gift to your ancestors and you, the same as I did to Shiloh. And as for you, I’m going to get rid of you, the same as I got rid of those old relatives of yours around Shiloh, your fellow Israelites in that former kingdom to the north.’

Who would believe in this message? The people had some mystic relationship with the temple as the Lord says:

3-7 “‘Clean up your act—the way you live, the things you do—so I can make my home with you in this place. Don’t for a minute believe the lies being spoken here—“This is God’s Temple, God’s Temple, God’s Temple!” Total nonsense! Only if you clean up your act (the way you live, the things you do), only if you do a total spring cleaning on the way you live and treat your neighbors, only if you quit exploiting the street people and orphans and widows, no longer taking advantage of innocent people on this very site and no longer destroying your souls by using this Temple as a front for other gods—only then will I move into your neighborhood. Only then will this country I gave your ancestors be my permanent home, my Temple.

There were false prophets saying that the Temple was a permanent home to the Lord, therefore, the Temple and the people were protected. It is similar to a church full of sins saying that the Lord will keep it alive because it is the house of the Lord.

Imagine how angry were the leaders of Judah when heard Jeremiah saying that the Lord will destroy his Temple and many will die; but despite that, Jeremiah was praying to the Lord for the Jews:

16-18 “And you, Jeremiah, don’t waste your time praying for this people. Don’t offer to make petitions or intercessions. Don’t bother me with them. I’m not listening. Can’t you see what they’re doing in all the villages of Judah and in the Jerusalem streets? Why, they’ve got the children gathering wood while the fathers build fires and the mothers make bread to be offered to ‘the Queen of Heaven’! And as if that weren’t bad enough, they go around pouring out libations to any other gods they come across, just to hurt me.

The Lord rejects religious sacrifices when mixed with sin:

1-23 “The Message from God-of-the-Angel-Armies, Israel’s God: ‘Go ahead! Put your burnt offerings with all your other sacrificial offerings and make a good meal for yourselves. I sure don’t want them! When I delivered your ancestors out of Egypt, I never said anything to them about wanting burnt offerings and sacrifices as such. But I did say this, commanded this: “Obey me. Do what I say and I will be your God and you will be my people. Live the way I tell you. Do what I command so that your lives will go well.”

This message tells me that the Lord rejects my religious offerings and even my time spent reading the Bible if I don't love the Lord as He is and if it doesn't translate into loving his sons and daughters.
