Take a moment and slowly read and consider this probing insight from Lewis. For, if you would want more of God, the condition of the man must be attended to:
When you come to knowing God, the initiative lies on His side. If He does not show Himself, nothing you can do will enable you to find Him. And, in fact, He shows much more of Himself to some people than to others – not because He has favourites, but because it is impossible for Him to show Himself to a man whose whole mind and character are in the wrong condition. Just as the sunlight, though it has no favourites, cannot be reflected in a dusty mirror as clearly as in a clean one.
You can put this another way by saying that while in other sciences the instruments you use are things external to yourself (things like microscopes and telescopes), the instrument through which you see God is your whole self. And if a man’s self is not kept clean and bright, his glimpse of God will be blurred – like the Moon seen through a dirty telescope.
That is why horrible nations have horrible religions: they have been looking at God through a dirty lens.
