Prayer can be liberating.
It requires letting go. Letting go means allowing yourself to experience vulnerability before God; allowing yourself to be weak and uncertain; allowing yourself to feel that you are being held by God.
When people complain that prayer leaves them unmoved, I remind them to let themselves feel small for a moment. I remind them that life is short and fraught with danger. Acknowledging God and asking for His support can bring solace and serenity.
