Interesting, a family, Father, children/sons, brothers/sisters.
Compare what Jesus said after his resurrection:
John 20:17 Jesus said to her: “Stop clinging to me, for I have not yet ascended to the Father. But go to my brothers and say to them, ‘I am ascending to my Father and your Father and to my God and your God.’”
Did you notice it? Father, brothers ... So Jesus is the brother of born again Christians, and all of them have only One God and Father.
Then: can trinitarians be born again this way?
If one's going to learn these 'writings' in a 'carnal' way of 'perspective', and 'out of context' determination character standing,
One will apparently end up on 'cross roads', and tend to question about it 'relentlessly', due to the fact one's ignorance to the 'context'.
We're able to 'feed' but we're unable to force the one to eat, if to that one such a food taste not like 'honey'.
Biblically, the only true GOD is 'invisible', and who's 'voice' no man is able to hear and understand, but they'll just drop dead in 'fear' and 'trembling'.
Therefore in the 'Old', HE had to use 'Moses', but yet have not reveal HIS Son, but the Son who in the 'spirit' and the 'form' of man visited Moses for the 'task', as He did to Abraham.
Only in the 'New', GOD decided to present HIS Son 'fully' and use Him in the 'task' to 'salvage' prisoners of 'sin' and 'death', and 'grant' them 'eternal life'.
Therefore also further 'discipling' them in 'context' about the Kingdom of GOD, as Himself 'God', 'King', 'Prophet' 'Judge', 'Father', 'Brother' and 'Friend' in 'person' and 'representation'.
Since in 'person' He is 'also' the 'full visible exact mirrored image' of the 'invisible GOD' in 'Heaven' and who art in 'secret', have come down to 'earth' in these last days.
The Son plays a wider role in regards 'creation', than the 'FATHER' who's above 'all', since the Son 'created' them and 'gave' them life 'in person'.
It 'pleased' the FATHER the Son 'do' so on His 'own', while the FATHER 'by', 'through' and 'for' the Son 'did' all these 'things'.
Therefore Biblically this is the 'context' and 'sound doctrine' from above of such, now who are we to 'question'?
Ones on 'earth', being a mere 'speck' of dust and 'clay' or even made a 'pot' by the 'Potter'?
Isn't it like a 'dog' who 'bites' back to what is given as 'good', or a 'swine' who 'trample' on one's cast 'precious pearls'?
