Ketkev: "But to be delivered from physical cursings does depend on the mercy and grace of God."
So you are telling me that if you learned how to fix your mistakes that you made health wise, that you must wait on God to decide whether to heal you or not? To me, when God brought me here and taught me to understand how to fix my health problems, that was His way of showing me His Mercy and Grace. If I was to ignore this info, it would be like ignoring God's direction for my life.
I still think you are trying to tell me that you have tried this protocol for your wife and it didn't work, so it must be God's will, she stay sick (for now) I say lets prove you right or wrong by getting to the meat of the problem and see if your protocol needs correcting. Let's see if your Faith matches your obedience.
Ketkev: "God does not owe us anything, but we are forever indebted to him. He doesn't owe us rewards for good choices, but by his grace and mercy he enables us to make good choices and then by his grace and mercy he often rewards us for those good choices."
Jesus paid the debt for me. I chose Him like a woman chooses a husband. He wooed me with His love and I accepted Him and I cleave to Him like any good wife does. I chose to love Him because He loved me first. He paid the price for the slaverly of sin I was in and in my graditude and love, I wish to please Him in all the things that I do. We made promises together, to love and cherish. No loving husband wants his wife to be ill.
