Hebrews 11:1-3 Now faith is the substance of things hoped for, the evidence of things not seen. For by it the elders obtained a good report. Through faith we understand that the worlds were framed by the word of God, so that things which are seen were not made of things which do appear.
More than the suffering, you can see faith in this simple request. The parent believes in God's healing power. He is waiting on Jesus to move in His situation. This is the kind of faith that moves mountains... mentioned in the Bible, the kind that brought about miracles. This is mustard seed faith.
Matthew 17:20 And Jesus said unto them, Because of your unbelief: for verily I say unto you, If ye have faith as a grain of mustard seed, ye shall say unto this mountain, Remove hence to yonder place; and it shall remove; and nothing shall be impossible unto you.
When you pray, remember Jacob. Jesus does.
