2 Corinthians 5
17 Therefore, if anyone
is in Christ,
he is a new creation; old things have passed away; behold, all things have become new. 18 Now all things
are of God, who has reconciled us to Himself through Jesus Christ, and has given us the ministry of reconciliation, 19 that is, that God was in Christ reconciling the world to Himself, not imputing their trespasses to them, and has committed to us the word of reconciliation.
I have never experienced what you have experienced, but you must know something. The God who created the universe is the same God that gave Himself up on the cross so that you could be forgiven and be called a Child of God. Thanks to His resurrection we are also promised to never die(spiritually). It is this same power that we have our hope and faith in. The power of the almighty God.
Just like the passage says up there, if you are in Christ you are a new creation. All your sin was nailed to the cross of Jesus, therefore you should also crucify your old self to it. You MUST believe this, you ARE a new creation. God has the power to heal you, He has healed other people from this. But you must not feed the fire. Don't feed your thoughts when they come. Instead when they do come seek God with all your heart.
Ephesians 6:10-18
New King James Version (NKJV)
The Whole Armor of God
10 Finally, my brethren, be strong in the Lord and in the power of His might. 11 Put on the whole armor of God, that you may be able to stand against the wiles of the devil. 12 For we do not wrestle against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this age,[
a] against spiritual
hosts of wickedness in the heavenly
places. 13 Therefore take up the whole armor of God, that you may be able to withstand in the evil day, and having done all, to stand.
14 Stand therefore, having girded your waist with truth, having put on the breastplate of righteousness, 15 and having shod your feet with the preparation of the gospel of peace; 16 above all, taking the shield of faith with which you will be able to quench all the fiery darts of the wicked one. 17 And take the helmet of salvation, and the sword of the Spirit, which is the word of God; 18 praying always with all prayer and supplication in the Spirit, being watchful to this end with all perseverance and supplication for all the saints—
The girdle of truth is what sustains the whole armor. Discerning right from wrong in the light of the scripture. It takes more than just prayer to do what you are seeking God to do for you. Confess your sins, repent from them because they lead to death, deny yourself, ask God to heal you, then follow Him through His word and prayer having the whole armor of God, because God will test you to build you up but satan will tempt you to break you down. There is nothing impossible for Him, but we must also do our part.
God bless you!
