“When He had said this, He spat on the ground, and made clay of the spittle, and applied the clay to his eyes” (John 9:6).
No less so than the man born blind, every believer has a storied encounter with Jesus that is unique to them. Yours may not have been a “Damascus Road” experience, but it is your experience. While there is nothing wrong with employing the rhetoric of apologetics to defend the Christian faith, the one thing that is irrefutable is your experience. It can be neither refuted nor argued against.
