John 1:12-13, "But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name: Which were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God."
If you are born-again, I mean, if you have received Jesus as the Lord of your life, the Bible said you are now a 'son of God'. God is the Creator of the world but He is not the Father to everyone, He is Father to only the people who received Jesus as the Lord of their lives. He gave them power to be called the sons of God. Meaning you can call Him Father, you can interact with Him, you are born of His Word, and God is His Word!
If you are the son of God, you have rights..just like you do in your earthly father's house. Your job is to find out your rights, make sure the devil does not rob you what's rightfully yours. The Bible said in Romans 8:16-17, "The Spirit itself beareth witness with our spirit, that we are the children of God: And if children, then heirs; heirs of God, and joint-heirs with Christ.." Knowing who you are in Christ is actually very very important else one can be tortured by the devil. This is one of the reasons why bad things may happen to a child of God...Galatians 4:1, "Now I say, That the heir, as long as he is a child, differeth nothing from a servant, though he be lord of all."
