I believe that anything that is said should be tested. Just because someone says they have discernment does not mean that they are immune from reacting, having wrong motives, or being wrong.
All of us need to test things , that’s biblical.
All of us need to pray for open hearts, minds, eyes and ears to hear and see if the Holy Spirit is part of what is being said.
Even a truth can be relayed without the Holy Spirit prompting it to be shared - truth shared at the right time and the right way can be used in a mighty way. Jesus always prayed and followed his father with regards to what he said, when he said it and how it was said ……. Often as not all of us can be guilty of sounding like resounding gongs !!
This is just my opinion xx
