What type of God do you worship that picks and chooses who he heals and who he doesn't heal? What type of Father would that be to select his favorites and ignore the request of His other children?

I am sorry, but some of us happen to believe the Bible. I am not sure what your authority for truth is, but it certainly is not God's word.

1. Paul sought for his own healing but God refused to heal him (2 Corinthians 12:7-10 [7] And lest I should be exalted above measure through the abundance of the revelations, there was given to me a thorn in the flesh, the messenger of Satan to buffet me, lest I should be exalted above measure. [8] For this thing I besought the Lord thrice, that it might depart from me. [9] And he said unto me, My grace is sufficient for thee: for my strength is made perfect in weakness. Most gladly therefore will I rather glory in my infirmities, that the power of Christ may rest upon me. [10] Therefore I take pleasure in infirmities, in reproaches, in necessities, in persecutions, in distresses for Christ's sake: for when I am weak, then am I strong.
   See All...). Paul came to see God's refusal to heal him as the greater blessing.
2. Paul, the same apostle who had earlier performed special miracles (Acts 19:11-12 [11] And God wrought special miracles by the hands of Paul: [12] So that from his body were brought unto the sick handkerchiefs or aprons, and the diseases departed from them, and the evil spirits went out of them.
   See All...), left Trophimus in Miletum sick late in his ministry (2 Timothy 4:20Erastus abode at Corinth: but Trophimus have I left at Miletum sick.
   See All...). The age of signs and miracles was definitely on the decline.
3. Paul rejoiced in the mercy of the Lord on Epaphroditus in healing him (Philippians 2:25-27
   See All...). Paul was full of heaviness because he heard that he had been sick and feared that he might have sorrow on sorrow. He clearly did not expect healing in every case, or he would not have sorrowed in such a way.
4. In fact, Paul took a doctor along with him (Colossians 4:14Luke, the beloved physician, and Demas, greet you.
   See All...) and gave a prescription to Timothy for his infirmities (1 Timothy 5:23Drink no longer water, but use a little wine for thy stomach's sake and thine often infirmities.
   See All...). Why did he not heal Timothy, if healing is for all God's children? You have no idea how far from scripture you have gone.
5. Contrast this with the early healing by the apostles when they "healed every one" (Acts 5:16There came also a multitude out of the cities round about unto Jerusalem, bringing sick folks, and them which were vexed with unclean spirits: and they were healed every one.

Fanny Crosby was blind from a child. She gloried so much in her infirmity that she said she would want to be born blind if she had it to do all over. Others, like you, accused her of lack of faith and sin because of her blindness. But look at the wonderful poetry and hymns that came from her hand. These hymns would probably not have come if she had normal sight. Your approach is shallow and false and it opens you to the wiles of the devil who comes as an angel of light (2 Corinthians 11:14And no marvel; for Satan himself is transformed into an angel of light.
See All...) and will deceive the whole earth by the miracles which he will perform (Revelation 13:14And deceiveth them that dwell on the earth by the means of those miracles which he had power to do in the sight of the beast; saying to them that dwell on the earth, that they should make an image to the beast, which had the wound by a sword, and did live.

Finally, you question the validity of a God who chooses who He heals and is not at the beck and command of His disciples. It is a dangerous thing to force God into our own preconceptions. You need to rethink what you are saying. God does not design His profile to please us. Rather, it is our entire purpose to please Him (Revelation 4:11Thou art worthy, O Lord, to receive glory and honour and power: for thou hast created all things, and for thy pleasure they are and were created.
See All...). It is certainly possible that you have turned to another god and that your rock is not my Rock, but I pray that you are truly born again or will become so and that the Lord will reveal His truth to you before you are further deceived by the devil.
