True, Christians are often spiritually ill. But you wouldn’t condemn a hospital because of all the sick people there, would you? People usually go to church because they NEED church. Church is a hospital for sinners rather than a country club for saints. Some churches may be better than others, just as some hospitals may be better than others. But you need a good “before and after” picture to accurately judge. If you meet a particularly wretched church-goer, don’t immediately blame it on the church. Ask yourself, “How much worse might this person be without his or her church?”.
You can change your pastor, you can change your church as well but you can't change your God
