In Noah's experience we get what are God's thoughts of the things around. Noah was to be separated from the old earth. If we look around now-take London for instance, is it a city in which God's children are to find rest of heart? No but a place they have to separate themselves from. Believers have to go through the world, but to keep themselves unspotted by it. By our very relations we often find ourselves hindered and interrupted, and cannot get separate for want of faith. We need the energy of faith. Noah's energy all flowed from faith following the line traced Out by God; and when the judgment came it found Noah in the ark, laid to rest there with his family; and God saw in it the expression of his faith, as a person separated by that faith to God.
