Pure in heart means to be sing-hearted... to will one thing- God. All (Jesus)'s moments flowed from His single-heartedness, from His intimacy with God. That was His core. Christianity is full of paradoxes and this is one of the strangest. When we are centered in God alone, we are able to relate to more of life and the world, and find more meaning in them. In some way a centered life becomes wider and fuller. To form one's life around this single perspective enables us to deal with more problems, not fewer, embrace more of life, not less of it. One reason is that we're not so divided, overwhelmed or bogged down by trivia and confusion.
