Jeremiah condemns religiosity. People were coming into the temple and saying they were worshiping the Lord but they were doing detestable things in God’s house. Do we misuse the church today? Would a modern day Jeremiah condemn our churches for religiosity or for practicing "churchianity" instead of Christianity?

Jer 7:22-23
For when I brought your forefathers out of Egypt and spoke to them, I did not just give them commands about burnt offerings and sacrifices, but I gave them this command: Obey me, and I will be your God and you will be my people. Walk in all the ways I command you, that it may go well with you.

God did not give the people these rituals and symbolic practices of burnt offerings and sacrifices in the beginning of the exodus from Egypt. All they had to do was to obey Him and walk in His commands. They had the Angel of His Presence (the pre-incarnate Jesus). It wasn’t until later that God added all the ritualistic regulations.

Exod 33:14
The LORD replied, "My Presence will go with you, and I will give you rest."

He was with them for heaven’s sake! All they had to do was to listen and obey Him.
Oops...He is with us too isn’t He? If we are believers, we have His Presence with us always in the form of the Holy Spirit. So, what’s our problem???

Jeremiah again rebukes the spiritual leaders.

Jer 8:11
They dress the wound of my people as though it were not serious. "Peace, peace," they say, when there is no peace.
The “falling away” from godly teaching started early. It was treated as a “scratch” when it was a “dagger” to the heart.

Jer 9:23-24
This is what the LORD says: "Let not the wise man boast of his wisdom or the strong man boast of his strength or the rich man boast of his riches, but let him who boasts boast about this: that he understands and knows me, that I am the LORD, who exercises kindness, justice and righteousness on earth, for in these I delight," declares the LORD.

2 Cor 1:12
Now this is our boast: Our conscience testifies that we have conducted ourselves in the world, and especially in our relations with you, in the holiness and sincerity that are from God. We have done so not according to worldly wisdom but according to God's grace.

What a boast…to conduct ourselves in holiness and sincerity because we understand and know the Lord!
