Uncircumcised in ear
This IPD uncircumsized in ear is concerning people that will not listen to when the word of God is spoken. Basically you can say scripture and they will not hear it.
Acts 7:51 Ye stiffnecked and uncircumcised in heart and ears, ye do always resist the Holy Ghost: as your fathers did, so do ye.
1 John 4:6 We are of God: he that knoweth God heareth us; he that is not of God heareth not us. Hereby know we the spirit of truth, and the spirit of error.
You can talk to them about things and they listen and then when you say some scripture their attention is just turned off or they suddenly start thinking about something else or you just notice they arent listening anymore. And if you ask them what you said, they cannot say what you said.
What should we do with someone that has uncircumcised ears?
Treat him or her as an unbeliever.
