What does the Bible say about God being our Father?

In John 20:17, Jesus declares, 'I ascend unto my Father and your Father, and to my God and your God,' highlighting the relational aspect of God as Father for believers. This indicates that those who believe in Christ are included in the family of God, as emphasized in Matthew 12:50, where Jesus states that those who do the will of His Father are His family. This familial relationship underscores the significance of obedience and faith in our connection with God, as we come to Him through Jesus Christ, who is our advocate and mediator.
