Why pray for personal intentions?
If God knows our hearts, our future, and what is best for us then what need is there to pray for private intentions?
If things don't go our way, then we say "oh, it must not be God's will", but if things go our way, then we say "God has heard our prayer!".
It is like a silly game and a waste of time. It seems just an emotional act of talking to oneself.
I am, of course, strictly referring about personal prayer for private intentions. Not prayers for adoration, holiness, or increase in virtue, but things like: "God, help me move somewhere else, or help me find a job, etc etc".
