.......No one would deny a little girl the opportunity to tell someone that she loves her father. Common sense tells us that Jesus wasnt forbidding this type of use of the word "father."
In fact, to forbid it would rob the address "Father" of its meaning when applied to God, for there would no longer be any earthly counterpart for the analogy of divine Fatherhood. The concept of Gods role as Father would be meaningless if we obliterated the concept of earthly fatherhood.
But in the Bible the concept of fatherhood is not restricted to just our earthly fathers and God. It is used to refer to people other than biological or legal fathers, and is used as a sign of respect to those with whom we have a special relationship.
For example, Joseph tells his brothers of a special fatherly relationship God had given him with the king of Egypt: "So it was not you who sent me here, but God; and he has made me a father to Pharaoh, and lord of all his house and ruler over all the land of Egypt" (Gen. 45:8).
Job indicates he played a fatherly role with the less fortunate: "I was a father to the poor, and I searched out the cause of him whom I did not know" (Job 29:16). And God himself declares that he will give a fatherly role to Eliakim, the steward of the house of David: "In that day I will call my servant Eliakim, the son of Hilkiah . . . and I will clothe him with [a] robe, and will bind [a] girdle on him, and will commit . . . authority to his hand; and he shall be a father to the inhabitants of Jerusalem and to the house of Judah" (Is. 22:2021).
This type of fatherhood not only applies to those who are wise counselors (like Joseph) or benefactors (like Job) or both (like Eliakim), it also applies to those who have a fatherly spiritual relationship with one. For example, Elisha cries, "My father, my father!" to Elijah as the latter is carried up to heaven in a whirlwind (2 Kgs. 2:12). Later, Elisha himself is called a father by the king of Israel (2 Kgs. 6:21).....
