If you find that your healing is not manifesting, then there may be demonic blockage.
The enemy uses a variety of tactics; inc
Spirits of Unbelief and doubt will bring unbelief that the Lord will heal you or doubt in His word.
“Let the wicked forsake his way, And the unrighteous man his thoughts; Let him return to the Lord, And He will have mercy on him; And to our God, For He will abundantly pardon.” Isaiah 55:7. Ungodly beliefs are unbelief.
Lying and deceiving spirits will make you believe that God doesn’t want to heal you. The enemy will sometimes bring false symptoms to make you believe the prayer is not working or speak lies to you that spiritual healing doesn’t exist today.
“And you shall know the truth, and the truth shall make you free.” John 8:32. Jesus, Father God, Holy Spirit and the entirety of the Word of God is the truth.
Spirit of un-forgiveness, “But if you do not forgive, neither will your Father in heaven forgive your trespasses.” Mark 11:26
Generational Curses, if you see several generations with the same sickness there may be generational curses, “keeping mercy for thousands, forgiving iniquity and transgression and sin, by no means clearing the guilty, visiting the iniquity of the fathers upon the children and the children’s children to the third and the fourth generation.” Exodus 34:7. Ask the Lord to forgive the sins of your forefathers and break the curses. Jesus was the curse on the cross.
Thank and Praise Him for your healing until you see the manifestation. The LORD saves, heals and delivers (Psalm 107:19-21).
