Listen to KnittedScarf (and everyone else) on this. I too used to cry out to God, in the middle of the night sometimes, "Why aren't you answering my prayers??!" I was in a 20-year sex-starved marriage, and as a man with a very high need for affection and physical touch, it was absolutely KILLING me.
"Change my wife's heart," I pleaded.
"Soften her heart towards me," I wailed.
"Holy Spirit, please move upon her heart and make her see how much I'm hurting," I cried.
Well, God had other plans for me, and for us, and they were different from what I thought they should be. Now, looking back, I can see how much I needed to grow, and strengthen. HE knew that, but I thought I knew better.
We often pray for a magic wand, NB, but God more often than not gives us a trowel. It's in the day-to-day little "digging" that we usually find ourselves, and grow stronger.
Pray for wisdom, and for CLARITY. And then pray for COURAGE, to do the right thing.
