Brother Lawrence has something to say about keeping focused on God rather than self. He mentioned that when his mind strays to things other than God, he confesses it and moves on in the presence of the Lord, or something like that. "Is that it?" I thought, "can it be so simple?" It can be. Certainly God does not delight in our sin, but He does not delight in our guilt for the sin either. Resorting to self-destruction, even in little doses, no matter what the reason, is not God's desire. Freedom comes long before it is experienced as freedom. Believing freedom exists to the extent to which it truly exists makes guilt and self-condemnation tantamount to silliness and absurdity.
PS Brother Lawrence is the fame of the book entitled, "The Practice of the Presnece of God."
