It is written in the Bible that God the Father so loved you that He gave His one and only Son, Jesus, so that everyone who believes in Jesus shall not perish but have everlasting life.
If you believe in Jesus as your Savior, you are declared righteous by faith, not by observing the Law. As it is written:
For Christ is the end of the law for righteousness to everyone who believes.
Once you have the "revelation" of how righteous you are by the blood of Jesus (not by your performance), you will receive your healing effortlessly. As it is written:
Christ purchased our freedom and redeemed us from the curse of the Law and its condemnation by becoming a curse for us.
You must know that sickness/disease is a curse. It's not from God. Jesus wants you well. That is always His will. Once you have the right believing (that you're not guilty anymore by the blood of Jesus), you will have the right results. God does not give sickness/disease to people to teach them lessons. You will never find Jesus did that in the gospel.
In summary, first believe that Jesus died for your sins and that He rose again the third day according to the Scriptures. Ask Him to come into your life (pray in your own words, from your heart, Jesus loves you). Then, keep on listening to sermons that are full of Jesus' blood that has cleansed you from *ALL* sin. Listen to sermons that are full of Jesus' Finished work at the cross that has made you righteous by faith (not by observing the law).
Here's a sermon by Pastor Henry that you can listen (again and again) for free.
About Pastor Henry
Pastor Henry is passionate about divine health and healing in honor of the Lord's mandate:
Heal the sick, raise the dead, cleanse those who have leprosy, drive out demons. Freely you have received, freely give (Matthew 10:8).
Over the years these acts are exactly what the Lord has done through Henry. Jesus, through Henry as the earthen vessel, healed those with back pains, raised a man from the dead, cleansed those with cancer and cast out demons. Personally Jesus healed Henry of serious infections and the Lord raised his own biological father from the brink of death. The Lord has also given him the revelation on divine health and he walks in it 24x7.
