Prayer for Potty Training

This sounds silly as I sit down to right it-- but we are need of some prayer. Pray that Patrick will take to the potty! He is over 3 and so so so resistant to do it. He knows all the right answers, he has done it, he loves it when he does go in the potty, but he just won't do it. He says he likes to go in his diaper. Oh someone help me! I know I need to back off. He is stubborn and strong willed and this has to be his decision. Anyhow-- any pointers out there? I am desperate!
