Pearl:With grace
Hebrews 13:9 Be not carried about with divers and strange doctrines. For it is a good thing that the heart be established with grace; not with meats, which have not profited them that have been occupied therein.
All these IPDs should not be how we try to interact with people. Rather we remove ourselves from them. Because it has not benefitted them that went before to have their heart established with divers doctrines.
Matthew 10:16 Behold, I send you forth as sheep in the midst of wolves: be ye therefore wise as serpents, and harmless as doves.
We should be innocent as doves. So its best to just shut up or try to be helpful and leave.
