How to Become a Child of God

“He came unto his own, and his own received him not. But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name: which were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God” (John 1:11-13).
HOW does a man become a Christian? The verses of the text, I believe, answer the question, and they do so first negatively and then positively. There are three ways indicated by which one cannot become a child of God, and only one way by which he can. Look at verse 13, “Which were born, not of blood, nor of the will of the flesh, nor of the will of man.”
