Kyle’s academic website is bkylekeltz.com, and he occasionally publishes apologetics/philosophy/theology lectures on YouTube (B. Kyle Keltz) and on PodBean (Philosophy Apologetics & Theology). Kyle was raised in a Christian home but was indifferent (and sometimes hostile) to Christianity until he became convinced that God must exist after studying philosophy of religion during his time in the military.

So, Kyle has devoted his life to studying and making sense out of philosophy, theology, and the Bible and being someone who can provide answers to people seeking truth as he was in his earlier years.
