We can be sons of God too, through adoption.
The reality of Sonship and the offer of adoption is one of the most significant distinctions between the One True God and the alternative “gods” presented in other religions. Other gods have no sons and/or they make no provision for mankind to be adopted as heirs.
He fell on the ground, and prayed that if it were possible, the hour might pass from Him. And He said, “Abba, Father, all things are possible for You. Take this cup away from Me; nevertheless, not what I will, but what You will.”
As many as are led by the Spirit of God, these are sons of God. 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.” The Spirit Himself bears witness with our spirit that we are children of God.
…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.
