God speaks efficaciously to His children. He does not stutter or stammer. He does not leave you hanging. You know it was God speaking to you because of the supernatural imposition of the event itself. In other words, it is not possible for you to adopt the belief that God had not spoken to you when, in fact, He had spoken to you.
Young evangelicals seem to view the practice of challenging orthodoxy through the lens of updating an outdated policy manual at work. The casual approach to such things is telling and reveals a very disturbing trend in many, if not most, evangelical churches. I believe this trend can be traced to the refusal of the Church to test those who claim to be believers and teachers and leaders who are not.
