Ephesians 4:14

That we henceforth be no more children, tossed to and fro, and carried about with every wind of doctrine, by the sleight of men, and cunning craftiness, whereby they lie in wait to deceive;

So we are no longer to be children, tossed back and forth by waves and carried about by every wind of teaching by the trickery of people who craftily carry out their deceitful schemes.
