"Show me God, then I will believe in him."

When I was in college, my Communist friend challenged me saying, "Show me God. Then, I will believe in him."

I struggled because I couldn't show him God.

I, then, got an inspiration from somewhere to ask him this question, "Do you have a mind?"

He said, "Of course I do."

Then I said, "Show me your mind. Then I believe you have one."

Then, he struggled.

Eventually he realized that he cannot deny God's existence only because he cannot visibly see God. I think this was a good realization for him (and me).

He also realized that the real reason why he denied God's existence was, in fact, not that God is invisible, but that he hated "religion" for some personal reasons. So, it was an emotional reason that he didn't want to believe in God.

Therefore, even if someone says, "I don't believe in God.", do not give up. You can find out why he doesn't want to believe in God or why he decided not to believe in God. Through that conversation with him, you (and maybe he also) might find God!
