Sonship is not a generic or gender designation but by its nature is a relational position. It has nothing to do with being female or male and everything to do with being just like the Father. It is not gender, but progeny.
Jesus spoke much about “knowing the Father,” and spoke of it, not only for himself, but also for us. He said, “All things have been handed over to me by my Father, and no one knows who the Son is except the Father, and who the Father is except the Son, and anyone to whom the Son wills to reveal Him.” We are to know the Father as Jesus knows Him, and to serve Him as Jesus served Him and to be to the Father what He was to the Father, a son.
Jesus knew God as Father and he served Him as Son. He was truly Son to God as God was Father to Him. It is a certain kind of truth that says, “no one knows God except the Son,” and the greater truth is that the only way to know the Father is to be a son. The only way to know God is to know Him as Father, for that is the only actual relation we can bear to Him. Most other thoughts of God will make for a mystical, untouchable and somewhere-out-there God. Father and son are family.
