This scene between elves and dwarves in The Fellowship of the Ring
“And the Dwarf, hearing the names given in his own ancient tongue, looked up and met her eyes; and it seemed to him that he looked suddenly into the heart of an enemy and saw there love and understanding. Wonder came into his face, and then he smiled in answer.” (Book 2, Chapter 7)
This should be happening regularly among believers, and then the watching world will see the reality of the gospel.
