i became a man and put away childish things
1 Corinthians 13 11 When I was a child, I spoke as a child, I understood as a child, I thought as a child; but when I became a man, I put away childish things. 12 For now we see in a mirror, darkly, but then face to face. Now I know in part, but then I shall know just as I also am known.
Child Is Father of the Man "Child is father of the man" is an idiom originating from the poem "My Heart Leaps Up" by William Wordsworth. In a 1966 interview, Wilson mistakenly attributed it to Karl Menninger, and added that the saying had fascinated him.[2] There exist many different interpretations of the phrase, the most popular of which is man being the product of habits and behavior developed in youth. According to collaborator Van Dyke Parks, he brought up the idiom to Wilson.[3]
