It may seem that, like a medicine that promises to make us well but makes us sick, our faith does not do what it claims to do. If Christians are not more like Christ than anyone else, why follow Christ? A biblical response is that our faith never promises that Christians will be made perfect in this life. Sanctification requires cooperation, which is why we are to “put to death what is earthly in you” (Colossians 3:5). Even Paul the Apostle admitted, “I do not do the good I want, but the evil I do not want is what I keep on doing” (Romans 7:19).
