Vital Parts Of The Body-Part IV (1 Cor 12:7-31)

Your child is in the hospital dying. You desperately pray for the Lord to heal them. Why does God apparently say “yes” to some parents and “no” to others? When Jesus was here on earth there were times when the sick in an entire town were brought to Jesus and he healed them all. Today there are recorded cases of miraculous healings, but many are left still languishing in their illness. Does this mean their faith is not strong enough? Is God simply not powerful enough to meet all of these desperate needs?
