The key I believe is God’s will and submission to his will. I too have seen the extraordinary. I do believe however it requires true heart alignment with God. This is the without doubt part. No doubt IN the Lord.No doubt that he will care for your needs and consider your request, no doubt that whatever he chooses is the RIGHT choice. That is the hardest part. As I prayed for my child in a coma whose life was dependent on doctors there was nothing else I could do. Through that prayer I was at last able to submit my will to God. I had to give my child back to the Lord and take my will off the situation. That included being ok if God called him. That was an ugly crying submission. One that took days. At the end of that submission 30 minutes later the surgeon came out and told us he had finally succeeded. Four surgeries 3 days in a coma. Literally the most difficult thing I have ever done was giving back what wasn’t mine to begin with.
