Hope this testimony is beneficial .... it is certainly for me.

...I can also tell you another story, that at a certain hour of a certain day in a certain month and certain year, God opened my eyes to see that Christ is my healing. This is something that cannot be repeated; it is something that cannot be quantified. Once is enough. It is not a thing that can be counted. It is a person, a personified healing. My healing is a person who is in me as my healing all the time. Praise the Lord that this is a fact. Having God heal me and having Him as my healing are two entirely different things. One is a thing; the other is a person.
Paul was not healed, but he received the healing. Can we see the difference between these two? Paul showed in 2 Corinthians 12 that he was not healed (v. 9). He did not receive the thing which we call healing. But with Paul, we see One who was his healing continually. His weakness remained with him, but his healing also remained with him. His weakness was chronic, but his healing was abiding. What is a healing? To us, a healing is the removal of something. No, healing is not a removal; healing is acquiring something. Healing is not the removal of weakness but the presence of strength.
When I first saw this matter, the light came very slowly because my mind was filled with things; everything around me was a thing. I did not realize that the Lord wanted to be my thing, and I did not know that healing was not a thing. I only knew that the Lord promised me something; I did not know that the Lord wanted to be my healing. I only knew about the Lord’s promise; I did not know about the Lord as my healing. One day I read Paul’s story in 2 Corinthians. It was very strange to me. It would have been an easy thing for the Lord to grant him the healing. Removing the thorn was as easy for the Lord as a doctor removing germs. But why did the Lord not heal Paul? I prayed about this, and while I was praying, the Lord showed me one thing. In 1923 Brother Weigh invited me to preach at a certain place. In order to get there, I had to take a little boat along the Min River. The boats often became stuck to the riverbed because the water was too shallow and the rocks were big. The boat owner often had to tug the boat along. While I was praying, this scene suddenly appeared in my mind. I said, "God, it would be easy for You to remove the rocks. Would it not be wonderful if You removed the rocks, and the boat floated on the water instead?" I read 2 Corinthians 12 and realized that this was exactly how Paul prayed. The water was too shallow, and the rocks were exposed conspicuously; Paul prayed that God would remove the rocks so that he could sail on the water once again. But God answered by saying that He would not remove the rocks. Instead, He caused the water level to rise. When the water rises, the boat can pass over the rocks. This is what God is doing. Our problem and our prayer are that we are only for a thing—healing. But His answer is for Him to be our healing. When He is present, we can glide over our problems. Paul’s weakness was still there; he did not use his own strength to fight it. If he fought with his own strength, he could only say that his own strength had tabernacled over him. But it was the power of Christ which tabernacled over him (v. 9). It was God who was working. There is a basic difference here.
One is God giving me a thing, and the other is God Himself becoming my thing. God in me becomes the thing that I need. God Himself is that very thing.
