We are truly being transformed today, into new godlike creatures despite of our corrupted and temporary bodies, beyond just in character of Jesus, we are partaking in the actual divine nature of God, through Jesus' spirit, and thus we are (being) spiritual brothers and sisters of Christ today for and into the Kingdom, of our common and shared one God, our Father.
Grace to you and peace be multiplied in the knowledge of God, and of Jesus our Lord.
Seeing that His divine power has granted to us all things that pertain to life and godliness, through the precise and correct knowledge of Him that called us by His own glory and virtue.
Whereby He has granted to us His precious and exceedingly great promises, that through these you may become partakers of the divine nature, having escaped from the corruption that is in that world by lust.
Yes and for this very cause you on your part should show all diligence; to your faith add virtue, and to virtue, knowledge.
And to your knowledge self-control, and to your self-control patience, and to your patience, reverence toward God.
And to your reverence toward God, brotherly kindness, and to your brotherly kindness, love.
For if these things are yours and abound, they make you to be neither idle nor unfruitful in the precise and correct knowledge of our Lord Jesus Christ.
For he that lacks these things is blind, seeing only what is near, having forgotten the cleansing from his old sins.
Wherefore brothers, give the more diligence to make your calling and election sure. For if you do these things, you shall never stumble.
For thus shall be richly supplied to you the entrance into the eternal kingdom of our Lord and Saviour Jesus Christ.
(2 Peter 1:2-11) NEV
The Bible describes Jesus as being our (spiritual and even immortal) brother three times: Hebrews 2:11, Romans 8:29, and Mark 3:34-35.
But we behold him who has been made a little lower than the angels- Jesus- crowned with glory and honour because of his suffering of death, whereby, by the grace of God, he tasted death for every person.
For it became Him for whom are all things and through whom are all things, in bringing many sons to glory, to make the author of their salvation perfect through sufferings.
For both he that sanctifies and they that are sanctified are all of the same nature. For this cause he is not ashamed to call them brothers, saying: I will declare Your name to my brothers, in the midst of the congregation will I sing Your praise.
And again: I will put my trust in Him. And again: Behold, I and the children whom God has given me.
Since then the children are sharers in flesh and blood, he also himself in like manner partook of the same nature; so that through his death he might bring to nothing him that had the power of death, that is, the Devil; and might deliver all those who through fear of death were all their lifetime subject to bondage.
For truly not to angels does he take hold in association; but he took hold of the seed of Abraham.
Therefore in all things he had to be made like his brothers, so that he might be a merciful and faithful High Priest in things pertaining to God, to make propitiation for the sins of the people.
For because he himself suffered when tempted, he is able to succour those who are being tempted.
(Heb 2:9-18) NEV
For whom He foreknew, He also foreordained to be conformed to the image of His Son, that he might be the firstborn among many other children. (Romans 8:29) NEV
And looking round on them that sat round about him, he said: Behold my mother and my brothers!
For whoever shall do the will of God, the same is my brother and sister and mother. (Mark 3:34-35) NEV
