Book of Mark : Jesus Praying in Solitude

I've always found it touching that the Bible mentions Jesus going off to spend some time alone. Sometimes churches focus almost entirely on "going out and witnessing" and "being a people person," and forget that some Christians are introverts who need time alone, for rest and meditation. I'm not sure whether Jesus would be classified as an "extrovert" or "introvert," but at any rate, verses like this show that He definitely needed time alone sometimes too!
