The toughest question I was ever asked, was by an elder in the church before I became a Christian. He asked me, “Have you thought about your soul?”: http://mbriley.preachersfiles.com/2008/10/05/have-you-thought-about-your-soul/
I was 15 years old at the time, and I had never been asked that question. For some time, my grandmother had been urging me to obey the gospel. After pondering this question in light of Scripture, I came to the conclusion that my soul was indeed in great jeopardy of being eternally lost.
I quickly decided that my soul was far more important than anything else I could imagine. There was no rational reason whatsoever to delay my obeying the Lord in baptism any longer, and thus I was baptized on January 1, 1960.
I’ve never regretted the decision.
