Ephesians 4:13-14

13In that way, all of us will become united, like one person. We will all believe in Jesus as the Son of God. We will all know him. We will become like a man who has grown up well. We will be completely as God wants us to be, just like Christ himself.

14So then we will not be like children any more. Our minds will not become confused by strange ideas. We will not change what we believe, from one thing to another. Some people teach things that are not true. They do clever things to deceive people. But we will not agree with their false message.
