There is … one God and Father of all, who is above all, and through all, and in you all. Ephesians 4:6

Only a person who believes on Jesus Christ can call God, Father; such a person has been adopted as God's son or daughter.

For you did not receive the spirit of bondage again to fear, but you received the Spirit of adoption by whom we cry out, "Abba, Father." Romans 8:15

And because you are sons, God has sent forth the Spirit of His Son into your hearts, crying out, "Abba, Father!" Therefore you are no longer a slave but a son, and if a son, then an heir of God through Christ. Galatians 4:6-7
