Charles Spurgeon Commentary Ephesians 4:14

"that we may be no longer children, tossed to and fro and carried about with every wind of doctrine, by the sleight of men, in craftiness, after the wiles of error;" — Ephesians 4:14 (ASV)

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; (Ephesians 4:14)

There are plenty of so-called Christians of that sort, nowadays, who are too weak to know anything for themselves.

They are not settled and grounded; the last person who comes near them and pulls their ear a little hard, turns their head his way. The next person, who will pull their ear a little harder, will turn their head another way.

Be no longer children, I urge you, brothers, but be men; know what you do know, hold it with the tenacious grip of a divinely-implanted faith, and God help you to escape from those who lie in wait to deceive!
