Yes, deliverance could come from prayers from personal gratification, prayers according to the words of God, and could be a mix of both. However, there are prayers and much more prayers of deliverance.  A holy and winning reference point is the time of prayer for deliverance according to God’s word. You might desire deliverance, but should be it only as it was consistent with God’s revealed word and will. No room for the unrighteous or unwise deliverance, but only deliverance according to the promises of God’s word will bring the real glory to God and actual blessing to us. That’s it!!!
