God is not a creature
Human beings are male or female, made with bodies and created in God's image. God is the Creator, not one more being within creation. Jesus tells the Samaritan woman that God is spirit, which helps us avoid picturing him as having a human body or biological sex like ours (John 4:24).
That does not make God distant or vague. The Bible says that both male and female human beings bear God's image (Genesis 1:27). So qualities we often label masculine or feminine, such as strength, tenderness, justice and compassion, all have their deepest source in God.
God is a Spirit: and they that worship him must worship him in spirit and in truth.
Why Scripture says Father
The Bible's masculine language is not merely a cultural habit that Christians are free to replace at will. God reveals himself as Father, and Jesus teaches his disciples to address God that way in prayer (Matthew 6:9). Jesus also speaks of the Father as distinct from the Son, while sharing fully in the work and life of God (John 14:9).
For that reason, using he, him and Father for God follows the pattern Scripture gives. It is not a claim that God is biologically male. Rather, it receives the relational name God has chosen to make known.
After this manner therefore pray ye: Our Father which art in heaven, Hallowed be thy name.
Motherly pictures matter too
Following biblical masculine pronouns should never lead us to treat women as less like God, or to squeeze God into narrow human stereotypes. Isaiah compares God's comfort to a mother's comfort for her child (Isaiah 66:13). Jesus describes his longing to gather Jerusalem's people with the protective care of a hen gathering her young (Luke 13:34).
These images do not rename God as a mother, but they do reveal his real tenderness. They correct any picture of Father that sounds cold, harsh or detached. God's fatherhood is the perfect source of all faithful parental love, not a copy of fallen human masculinity.
As one whom his mother comforteth, so will I comfort you; and ye shall be comforted in Jerusalem.
Speak with reverence and care
So there is good reason not to stop using the masculine pronouns and names Scripture uses for God. They help us speak about God as he has made himself known. At the same time, we can explain gently what those words do and do not mean, especially when someone has been hurt by controlling ideas of gender or fatherhood.
Jesus, the eternal Son, truly became a man in history, not as a statement that men matter more than women, but to save people of every kind. In Christ, men and women share equal standing as God's children and heirs of his promise (Galatians 3:28). Read these passages for yourself, and let Scripture shape both your words and your picture of God.
