Paul implies that the moral and spiritual immaturity of the Corinthian church prevented him from imparting deeper wisdom to them (“solid food” and not “milk” 1 Cor. 3:1-3).
The practical implication of this qualification is that Christians who begin to practice willful, repeated sin (and even—or especially—pastors and scholars who begin to practice willful, repeated sin!) will likely soon begin to lose sound judgment in interpretation and will become less and less able to understand Scripture rightly.
