My prayer

Over the last few years my prayers have changed. I used to pray that I'd conceive, beg really. And each month I'd be disappointed and angry. Why wasn't God hearing my prayers? Was I not doing it right? Not saying the right words? Was I not sincere enough? 
But God is the all-knowing one, not me. I can't sway his mind or force his hand. The power of prayer is not changing God, it's asking for the strength to change me.
Now instead I try to pray that God would protect my heart. That I would know peace and contentment with the blessings I already have. That I would trust in his wisdom and timing. I'm still sad every month, but not angry. Not like I was.
