But of the Son he says, Your seat of power, O God, is forever and ever; and the rod of your kingdom is a rod of righteousness. You have been a lover of righteousness and a hater of evil; and so God, your God, has put the oil of joy on your head more than on the heads of those who are with you. You, Lord, at the first did put the earth on its base, and the heavens are the works of your hands. Heb. 1; 5
The same goes for Christ; when God poured his Spirit into Jesus at his baptism, he confirmed that he had begotten a son in Jesus.
And there was a voice from the cloud saying, This is my Son, the man of my selection. Lu 9:35
As it says in the second Psalm, You are my Son; this day I have given you being. Ac 13:33
This sonship is inherent to the Spirit, which is the Son of God in our dimension.
And all those who are guided by the Spirit of God are sons of God…the spirit of sons was given to you, by which we say, Abba, Father. Ro 8:14
And because you are sons, God has sent out the Spirit of his Son into our hearts, saying, Abba, Father. Ga 4:6
Of course these are Christian writings, but this is also said in Jewish writings;
I said, You are gods; all of you are the sons of the Most High. Ps 82:6
And I shall create for them a holy spirit, and I shall purify them so that they will not turn away from following me from that day and forever. And their souls will cleave to me and to all my commendments. And they will do my commandments. And I shall be a father to them, and they will be sons to me. And they will all be called 'Sons of the living God.' And every angel and spirit will know and acknowledgethat they are my sons and I am their father in uprightness and righteousness. And I shal love them. Jubilees 1;24
