The following article helps to explain these aspects: Why Doesn't God Heal Everyone?
An abbreviated version is given below.
God is sovereign, and since he created us, he knows us perfectly. He therefore knows what is best for us at any given time in our lives. We may think, “I just want this sickness or disability or pain to go away”, but God sometimes uses suffering to accomplish different things in our life, which ultimately benefit us far more than suffering for a time. Eg this can draw us closer into relationship with him, developing our love, patience, perseverance and to keep us from becoming proud etc. Understanding that God’s timing is perfect can also help us to come to terms with suffering. The Bible has some things to say which describe parts of God’s plan:
We can learn to reprogram our thinking, so that through the Holy Spirit, we can think and become like Jesus.
“For who hath known the mind of the Lord, that he may instruct him? But we have the mind of Christ.”(1 Corinthians 2:16).
“Now the Lord is the Spirit; and where the Spirit of the Lord is, there is liberty. But we all, with unveiled face, beholding as in a mirror the glory of the Lord, are being transformed into the same image from glory to glory, just as by the Spirit of the Lord.”(2 Corinthians 3:17-18).
We are changed image:
Biblically speaking there are a number of things which can slow down or even stop your healing from happening:
Doubt.
“Jesus replied, “Truly I tell you, if you have faith and do not doubt, not only can you do what was done to the fig tree, but also you can say to this mountain, ‘Go, throw yourself into the sea,’ and it will be done.”(Matthew 21:21).
Unbelief
“And whatever things you ask in prayer, believing, you will receive.”(Matthew 21:22)
Lack of faith
God’s grace, which is described as undeserved favour, is received through faith.
“The mind governed by the flesh is death, but the mind governed by the Spirit is life and peace” (Romans 8:6).
“But let him ask in faith, nothing wavering. For he that wavereth is like a wave of the sea driven with the wind and tossed. For let not that man think that he shall receive any thing of the Lord.”(James 1:6-7)
Asking wrongly.
“Yet you do not have because you do not ask. You ask and do not receive, because you ask amiss, that you may spend it on your pleasures.”(James 4:2-3).
" If you believe, you will receive whatever you ask for in prayer.”(Matthew 21:22). Here, believing is essential to receive.
“So I say to you, ask, and it will be given to you; seek, and you will find; knock, and it will be opened to you. For everyone who asks, receives; and he who seeks, finds; and to him who knocks, it will be opened." (Luke 11:9-10). The sense here is that of keep on asking, not giving up.
"Ask" image:
"Be anxious for nothing, but in everything by prayer and supplication with thanksgiving let your requests be made known to God."(Philippians 4:6). Supplication has a sense of devotion and reverence for a holy God.
Unconfessed sin
Is anyone among you sick? Let them call the elders of the church to pray over them and anoint them with oil in the name of the Lord. And the prayer offered in faith will make the sick person well; the Lord will raise them up. If they have sinned, they will be forgiven. Therefore confess your sins to each other and pray for each other so that you may be healed. The prayer of a righteous person is powerful and effective.”(James 5:14-16).
