Wining
1Tim 5:23 "No longer drink only water, but use a little wine for your stomach’s sake and your frequent infirmities."
Christians then and now generally tried to avoid wine as it could lead to drunkenness. Timothy had probably given up wine altogether to avoid any appearance of impropriety. But there is always danger that such scruples may lead to legalism, if one forgets the freedom we have in Christ.
Another aspect of this verse is that in contrast to the health and wealth gospel today, the early Christians recognized that such infirmities were part of the Christian life - that God ordained Christians to suffer in the flesh just as non-Christians do - and that suffering doesn't necessarily have to do with sin. For we see that Paul did not view Timothy's suffering as a result of some kind of sin. Nor do we see Paul tell Timothy that he was suffering because of his lack of faith. Furthermore, contrary to that modern deviant theology known as "Christian Science" which advocates healing by faith alone, Paul recommended a medical remedy.
