13:11
John had expected to be changed and to be different in every way , but he did not know that , in order to realize his desire to be a `` man after God 's own heart , '' he must commence at the beginning and be as a little child again . But he was willing ; for he saw how his past life had been completely wasted , and he was glad to begin anew . In the second chapter of I Peter , John found much encouragement , also in I Cor . 13:11 , where he read : `` When I was a child , I thought as a child : but when I became a man , I put away childish things . '' Again he was determined to become a man , and to develop as quickly as possible . From that time on he availed himself of every opportunity to do good to all mankind , and this was no hardship . His great whole-hearted nature made him love to do good and to be a help to all who were in need .
