I think there is immense variety in the experiences of people as they come into faith and spirituality. I was raised in an atheist household, but i had a powerful conversion experience at an early age(20) when I was not in church- and never had been since a one time Sunday school attendance at the age of 6.
Rather than go into the details of my experience I would just like to say that as believer for over 40 years I have met so many beautiful people who have had such diverse experiences- from someone who always felt they knew Jesus since childhood to people who just gradually came to believe in Jesus Christ over a long period and couldn’t tell you a “day” when they were “converted” if their life depended on it.
I think to judge someone’s testimony of faith is difficult and perhaps a little presumptuous. Perhaps something does not ring true or seem scriptural, and I have seen and heard a lot of bogus spiritual stuff along the way, but to say things like “If you dont know when you were saved you probably arent saved”(which I have heard in certain Fundamentalist and Pentecostal circles) or “I am highly suspicious of anyone who claims to have had a supernatural spiritual experience with God”(which I have heard in certain Fundamentalist and Evangelical circles) is really kind of arrogant.
I think God’s Spirit reaches people in many different ways to reveal Jesus as Savior and Lord, so that there are too many beautiful experiences to put in a religious box or stamp on a ticket for admission to His grace and love. I have always been most touched by testimonies of people who had no earth shaking experience like my own, but just found themselves walking hand in hand with the Savior at some point, and serving in some quiet way.
