sons and daughters of God

What does Jesus mean when he speaks in John 10:34? Many churchmen of today as well as most of the Rabbi's of yesterday did not like Him saying He was the Son of God. They cannot even conceive of His meaning in speaking of the Spirit which is, being born again. We are all, He clearly seems to be speaking, brought into existence, born as children of the Holy Spirit, the Holy Spirit which is to say of existence. (I am that I am.) So then we are all, those who accept and believe, sons and daughters of God. Some speak of Jesus as our elder brother.
