When Are You Holy?

My friend asked me, "When are you the most holy?" I love his questions because he is a deep thinker and I knew something was spinning around in his mind.
"I don't know."
"When you are in fellowship, because Jesus says he will join two. So then Jesus is with you when you are with others." I have been meditating on that idea and I love the concept. But I don't think that is the case for me.
When I am faced with the greatness of God, is when I feel the closest to him. This picture reminds me of my time with God. Sometimes, nature makes me feel so small and God so big. It is his great power, compassion that humbles me and I feel so close to God. A mighty God humbles my heart; and I am filled with deepest appreciation. How about you?
