That is all fine and good. If you remember from my testimony (first bullet point), I began my spiritual journey as a child.
If you noticed, I ended my list with: "Yet whatever gains I had, these I have come to regard as loss because of Christ. More than that, I regard everything as loss because of the surpassing value of knowing Christ Jesus my Lord" (Philippians 3:7–8 NRSV).
I do not usually give out my credentials because some will either dismiss them or accuse me of hubris. However, since my opponent used his to demonstrate some kind of authority, I simply did what Paul did in Philippians 3.
