Every example of healing in the scriptures whether spiritual or physical was accomplished when men and women became determined and or desperate for something miraculous to happen in their lives. In all of these situation Jesus said to them: "you have great faith" or "your faith has made you whole."
In Mk. 10 Jesus heals the blind man. The blind man is yelling with desperation. "Son of David have mercy on me." He was yelling so loud that those around Jesus were becoming annoyed by him. But blind Bartimaeus yelled all the more. Here we have a man yelling to Jesus with all of his heart. In desperation and with determination he desires mercy from Jesus as to have his sight restored. And what did Jesus do? He had mercy on him and healed him. And Jesus said to him: "Go thy way; thy faith hath made thee whole."
Another example of whole heartedness is found in Mk. 5. The woman with the issue of blood. She had suffered with this sickness for twelve years and had depleted all of her resources as to be healed of this plague but it had only gotten worse. She was desperate and determined to press through the crowd and just touch the hem of Jesus garment. She knew that if she could do this she would be healed. And she did just that, and Jesus felt healing issue flow out of Him and He immediately turned around and asked: "Who touched me?" Once again Jesus says: "Thy faith has made thee whole; go in peace, and be whole of thy plague."
There are so many other examples of whole hearted faith and determination in the Word of God. Zacchaeus, climbing the tree just to get a glimpse of Jesus. Jesus seeing his desperation went to his house later and his whole household was saved. The centurion with the sick servant said to Jesus: "Just speak the word and my servant will be healed." The woman who washed Jesus feet. Her sin was great and she was desperate for much forgiveness, so with all of her heart she washed Jesus feet with her tears and dried them with her hair. These are all examples of great faith, desperation and determination to be healed as to have salvation come to them. Every time in these instances Jesus says: "Salvation has come to you." Whether they were healed spiritually or physically.. Salvation was theirs.. Their faith was pleasing to Jesus and their faith had saved them.
The Word of God says that faith is what pleases Him. God desires powerful, determined, desperate and persistent faith from us in receiving answers to our prayers. Please don't misunderstand, I am not talking about extreme emotions of the flesh here. I am talking about the zeal of our spirits which unite with the Holy Spirit. A faith that doesn't budge. It is steadfast, focused and sees the victory. Pressing in and praying through until there is a breakthrough in the spiritual realm. In that moment the power of the Holy Spirit is at work in us. Jesus interceding for us and in agreement with us. This is praying the will of the Father. If you have experienced this interlocking connection of the Holy Spirit with your spirit while in prayer, you will understand when I say, "That this is the power of God at work in you producing His will and His good pleasure in your life." This is the ultimate prayer of agreement because it is in agreement with Jesus Christ Himself for our lives, which brings the victory!
For it is God which worketh in you both to will and to do of His good pleasure (Phil. 2:13)
