Okay. So I am chronically ill. I was raised in a Christian family. My mum kept telling me Jesus would heal me. But after time I realised my belief in him and prayers were doing nothing. Even when I tried sincerely to hold onto the faith. So I became atheist. But every now and again I still get the urge to pray. So I pray to other deities from other religions since Jesus didn't respond. Well, mostly Hindu deities since I like Hinduism (Durga/Shiva). But still nothing.
Maybe I should try praying to as many different gods as possible from as many different pantheons and see if any of them decide to respond and help me? Maybe I should at least try it. I don't think gods are really out there, but maybe if they are one will actually show themselves to me. Why should I believe in a being that supposedly has the power to manifest itself but doesn't? Are they not real? Do they just not care? Maybe they are not really powerful afterall?
Too bad you were not getting the information you need to cope with your problem, to understand what is, and what will not be now.
I do not know if you read your Bible. Do you know the story about Jacob and how he had to work for his wife which turned into wives. He wanted to marry Rachel (if memory serves) but was tricked into marrying Leah. In the end, he had those two and their concubines.
The point is, God obviously wanted 12 tribes plus the priestly one. He could easily have given Rachel what she needed to produce all of them; instead, as it happened, Rachel died in childbirth after the 2nd child was born.
God. did. not. fix. her ! Moses had an impediment of speech. God did not fix this! My wife has begun to have mental problems by reason of age. God does not fix it. Paul asked for his eye ailment to be removed three times. He was told to stop asking for this.
In this world we live in, Christians have the hope of Paradise on earth under kingdom rule. Then things shall be fixed:
Rev 21: Behold, the tabernacle of God is with men, and he shall tabernacle with them, and they shall be his people, and God himself shall be with them, their God. 4 And he shall wipe away every tear from their eyes; and death shall not exist any more, nor grief, nor cry, nor distress shall exist any more, for the former things have passed away.
The promise by God to fix ailments is for Paradise, not know. What happened when Jesus walked the earth, and his apostles, was a taste of things to come, proof of what God can do.
If you have a problem, you may get the best results if you ask for guidance to the best doctor and best treatment, best medicine. At times, God gives this without us asking when an emergency arises. My grandson was visiting from far away, and went swimming where he got seriously stung by some critter. On the way to the hospital, the ambulance was diverted to a hospital that just happened to have the most eminent doctor for treating this kind of thing. The teenager still needed treatment, and had to endure pain. But, he got the best treatment possible.
The promise is that if we pray according to the will of God, then, and only then shall it be granted if we live righteous lives in Christ. It is not God's will that we presently live without disease and without dying. We are mortal and shall die. After the kingdom has been established pain and illness will be no more.
