Resolve never to forget the eye of God. The eye of God! Think of that. Everywhere, in every house, in every field, in every room, in every company, alone or in a crowd, the eye of God is always on you. “The eyes of the Lord are everywhere, keeping watch on the wicked and the good” (Proverbs 15:3), and they are eyes that read hearts as well as actions.
