And behold, there was a woman who had a spirit of infirmity eighteen years, and was bent over and could in no way raise herself up. But when Jesus saw her, He called her to Him and said to her, “Woman, you are loosed from your infirmity.” And He laid His hands on her, and immediately she was made straight, and glorified God. Luke 13:11-13
Jesus heals for one purpose; to bring glory to His name.

In this story Jesus saw the crippled lady and reached out to her. He spoke words of healing to her and laid His hands on her. She was immediately healed and gave the glory to God.
Recently, I have been deeply touched by the desire of God to heal those with diseases and infirmities. At this very moment God is healing people all over the world. I have seen His healing work on many occasions.
The act of healing begins with reaching out to God with repentance for your sins. Ask Jesus to cover you with His blood.
Seek out Jesus and ask Him to reveal any sins or mistakes from the past that might be preventing healing.
Many times your illness is a result of a genetic disposition passed on to you through your ancestry. Ask God to break the power of this stronghold and set you free.
Pray that all curses spoken over you in the past are broken by the blood of Jesus.
Healing will only come by your faith in Jesus. He died on the Cross so you can be healed.
Seek out Jesus by faith and praise Him for who He is. He keeps His word.
