A.W. Tozer addresses the issue of unlovely religious people, emphasizing that the sins of the spirit are more severe than those of the body. He illustrates how Jesus was a friend to publicans and harlots while opposing the Pharisees, highlighting that religious individuals often harbor inward sins that are more insidious. Tozer points out that while careless sinners may express their sins outwardly, religious sinners tend to conceal their iniquities, leading to a compressed state of moral tension. This inward sinfulness contributes to the unloveliness observed in many who practice religion without true heart transformation. Ultimately, all sin is fatal to the soul unless forgiven and cleansed.
