These people are gripers and complainers, living according to their own [evil] desires, whose mouths speak boastfully, and who show partiality [toward certain people] to gain some advantage.
[Although] their talk is big, what they say is worthless, and by [offering people] fleshly desires [i.e., sexual gratification], they lead people astray, who are barely escaping from the error of the world.
Look, even though ships are huge and are driven by strong winds, still their direction can be governed by a very small rudder, wherever the pilot desires to sail.
