But, peace to you on this issue..I just don't like any language that hints about Word of Faith teachings. They are a bunch of kooks. However I totally agree with your position on this. I believe that struggling individuals can be caused to stumble in their earnest attempts to defeat sin by claims that defeat is inevitable. Actually, Satan's defeat is inevitable, but on some issues the believer may be struggling with them until he dies.
Good points... so, in your mind, for someone truly asking about complete healing of addiction, as the OP was... would it be better to tell him the truth, that there are many, MANY Bible believing, God fearing, saved individuals that have had, and maybe will still have an occasional slip on their road to recovery.... or, to give a blanket statement that says that "if you give your heart to Jesus, all your physical addictions will be instantly HEALED" .... only to have that person experience a slip, just like MANY other Christians have done, and lose his faith because he was not "instantly healed" as "someone" had promised?
