The Lord replies and it is a reproof to Jeremiah: ‘Therefore thus saith the LORD, If thou return, then will I bring thee again, and thou shalt stand before me.’ This is not said to the Israelites; it is not to Judah; it is to Jeremiah.
This text and many others in the Scripture just the same, announces a solemn principle. You cannot be culturally relevant as some people put it. They say to their churches in their group, ‘You must be culturally relevant.’ But God says, ‘Speak to them, but don't go with them. Answer their questions; respond to them, but don't accept any invitations to do as they do, or to work with them. That is God’s command to Jeremiah: ‘You keep your distance. As far as participation with their lifestyle, their culture, their opinions; you are to be aloof from that entirely.’
Now that is what Bible believing Christians always used to say, until not so long ago, and this was the recognised principle of all churches everywhere. You never heard any of this: ‘be culturally progressive’. That didn't start to come in until the 1970s. Rather, what we heard was: ‘Pray every day; witness every day; follow the Lord; separate from the world. You are in the world, but you are not of it.’ Now it is entirely different. The Scriptural standard for generations and centuries has been cast aside. But the people of God who are faithful and trusting, will be as a brazen wall, and will be held and kept, and will call out the remnant that God has in his elected purpose.
