If there is a God, there is a map. If God has a map, his map is the true map.
Only God is to be loved for His own sake. Everything else is to be loved for God's sake.
Without that freedom to sin there is also no freedom to love.
Philosophy has degenerated into ideology.
We cannot hate truth in general, all truth, as we cannot hate food in general, all food. But we can hate a particular truth even though it is good for us, as we can hate a particular food even though it is good for us.
We sinned for no reason but an incomprehensible lack of love, and He saved us for no reason but an incomprehensible excess of love.
