The "Every Wind of Doctrine" Problem

Ephesians 4:14 says that we should no longer be children tossed to and fro and carried about with every wind of doctrine, by trickery of men. From this statement we know that obviously the early church struggled with internal struggles from the "trickery of men." How about the end-times remnant church? Does it face internal struggles from the "trickery of men?" It's doubtful any Seventh-day Adventist would say "no." But the problem is that everyone thinks those in the "other group" are the ones being tricked, being "carried about with every wind of doctrine." That being the case, how do we know for sure **we** are not the ones being tricked, and carried about by every wind of doctrine?  For further study, see: "What Is the Spirit of Prophecy?
