Are you saying then that Lord Jesus and the Apostle Paul both lied
Gr8grace lies all the time about Jesus, especially when he says Jesus loves us.
I was speaking on the behalf that he said we are to mind our own business, as nowhere in scripture does it say or show that.
We are called to love, help, do for, exhort, esteem, and teach and lead them in truth in His word. This nowhere says mind your own business, and both Jesus and Paul both give passages on dealing with the sinful behaviors on those called our brethren.
Paul even says do not associate with a person named a brother who continues to live a deliberate sinful lifestyle, and says to not even eat with them.
