Examine a man’s prayers and you will see how he relates to God.
If he asks for things (e.g. serenity, courage, wisdom, peace, confidence, good weather, rain, good fortune, one last chance, etc), he sees himself as being separate from God. If, however, he seizes upon prayer as an opportunity to radiate the blessings of God into the earth of his present circumstances, he sees himself as being one with God.
The former asks God “What’s in it for me?”; the latter asks himself: “What’s in it for Him?”
