Common misconception... pain and suffering does not make one a better person.
If it did, then why are we not all beating each other with hammers??? That would certainly lead to some pain and suffering!
Besides. God's Word teaches that He has already healed you:
1 Peter 2:24
Jesus carried our sins in his own body on the cross, so that we, being dead to sin, should live unto righteousness: by whose stripes you were healed.
Matthew 8:17
That it might be fulfilled which was spoken by Esaias the prophet, saying, Himself took our infirmities, and bare our sicknesses.
Isaiah 53:4, 5
Jesus has carried our grief (pain, anxiety, calamity, disease, sickness), and carried our sorrows (anguish, affliction, feelings of pain, sadness and sorrow): yet we did esteem Him stricken, smitten of God, and afflicted....but He was wounded (to wound, to break, be slain or killed) for our transgressions, He was bruised (crush, destroy, oppress, to collapse) for our iniquities: the punishment (violence, rebuke) of our peace was upon Him; and with His stripes we are healed. (He took our wounds, so we could take his wholeness & health in every area of life)
I always find it odd that people claim to be saved... even though they are not in Heaven yet, but the claim to believe what God's Word says about salvation and they stake their claim... "I am born again!" which is using the word of faith paul spoke of in Romans 10:9-10
But, if we look at what the Lord said thru Paul (and in Mark 11:23,24) we see that confession is made unto deliverance (salvation)
So, seeing Jesus has taken our physical pain and suffering upon Himself... why not agree with the work He did on the Cross and say / believe / act (with thanksgiving that God watches over His Word to perform it cause He's not a liar - Jeremiah 1:12) like you don't have to have pain and suffering in your body cause Jesus already paid for that and the pain and suffering must go!
We do this same thing with salvation... even at times when we don't feel saved, act saved, or talk like one that is saved... we keep saying we are saved, and yet refuse to do this concerning other promises of God.
Maybe we should do what the Lord said in this verse:
Colossians 2:6
As ye have therefore received Christ Jesus the Lord, so walk ye in him
I know it works when we start believing what God says over and above our feelings and circumstances and continue waiting upon the Lord for understanding standing on James 1:5
