This name of ‘Father,’ accordingly, is not a metaphor derived from the earth and attributed to God. Exactly the opposite is true: fatherhood on earth is but a distant and vague reflection of the fatherhood of God (Eph. 3:14-15). God is Father in the true and complete sense of the term. Among humans a father is also someone else’s son, and a son in turn becomes a father. Here, too, a father cannot bring forth a son by himself; fatherhood is temporary and accidental, not essentially bound up with being human. It starts relatively late in life; it also ends rather soon, in any case at death. But in God all this is different. He is solely, purely, and totally Father. He is Father alone; he is Father by nature and Father eternally, without beginning or end. For that reason also generation has to be eternal, for if the Son were not eternal, the Father could not be eternal either. The eternity of the Father carries with it the eternity of the Son. Addressing God as Father, one by implication also addresses the Son. —Herman Bavinck, Reformed Dogmatics
