William Burkitt on 2 Timothy 3:13

Our apostle having acquainted us, in the former verse, with the condition of the godly, that they must expect and prepare for persecution; he lets us in this verse understand the miserable condition of the wicked, that they wax worse and worse; their proficiency is mere apostasy, they actively deceive others, and are passively deceived themselves, by the devil, that lying spirit, that grand imposter.

Learn hence, That the prosperous estate of wicked men is much more dangerous and miserable than the afflicted, persecuted conditon of the godly; the good by persecution grow better, but the wicked by living easy wax worse and worse.
