One of the things that Jesus urged was simplicity, recommending that people become like little children (Matt. 18:3). Elsewhere Paul talked about putting childish ways behind him and growing up (1 Cor. 13). Why is that? Is this one of those glaring contradictions that would-be debunkers of the Bible like to point out? How do you resolve this? In what ways should we be like children and in what ways like adults?
