Paul's description of end-times moral corruption includes the warning that people will have the appearance of godliness while denying its power, making them dangerous influences who prey on vulnerable individuals. His reminder that all Scripture is God-breathed and profitable for teaching, reproof, correction, and training in righteousness equips believers for every good work and provides the standard for evaluating all spiritual claims. The solemn charge to preach the word in season and out of season takes on urgency as Paul faces execution, while his confidence in receiving the crown of righteousness demonstrates hope grounded in divine faithfulness rather than personal achievement.
