If you have trouble getting your head around the truth that recovery in it's worldly sense is not needed from a biblical stance - then you have a faith issue.
"Many people are willing to believe regarding those things that seem probable to them. Faith has nothing to do with probabilities. The province of faith begins where probabilities cease and sight and sense fail. Appearances are not to be taken into account. The question is - whether God has spoken it in His Word." - George Mueller
Consider that the more horrific and hopeless a sinners condition may appear, how by appearances there may seem to be no way that the simple gospel truth could ever have power in a mind seemingly destroyed by the power of sin. Then consider the awesome glory that will be brought to God by the transforming of that sinner into a shining child of God by the power of the Holy Spirit through the simple, faithful sharing of the gospel of Jesus Christ.
So faith comes from hearing, and hearing through the word of Christ. - Romans 10:17
