It is my current understanding that mainstream Christians do consider themselves to be figuratively the children of the Father (as opposed to literally).
Why is this? Which Bible verses lend themselves to this idea?
(I'm seeking understanding of the perspective here, please avoid any arguing).
One example:
"
For you did not receive the spirit of slavery to fall back into fear, but you have received the Spirit of adoption as sons, by whom we cry,' Abba! Father!' The Spirit Himself testifies with our spirit that we are children of God, and if children, heirs also, heirs of God and fellow heirs with Christ, if indeed we suffer with Him so that we may also be glorified with Him." - Romans 8:15-17
We are children of God the Father by adoption, that is, by grace. Because we, having been joined to Christ by the mercy of God and having received the Holy Spirit are found in Christ, thus we have Christ's Father as our Father. He is called Father because He is the God and Father of our Lord Jesus Christ, He is only our Father
by grace, by adoption, through faith, etc.
God has no literal (that is, biological, natural, etc) offspring because God is God, He's not a male, He's not an creature. God is God.
In the Trinity there is the Father, Son, and the Holy Spirit.
The Father is called Father because He is Father of the Son, just as the Son is called Son because He is Son of the Father. The Son is uncreated, eternal, there was never a time the Son was not, and so the Father has always had His Son. If the Father is uncreated, without beginning, having always been and always being then the same is true of His Son; and it is through the Son--who became man as Jesus--that we have heard God called Father, as it is Jesus--the eternal Son--who points back to His Father, revealing Him to us. And so if we have seen the Son we have seen the Father, and if we have known the Son we have known the Father, for the Son makes the Father known (John 1:18); and therefore Christ has come and revealed the Father and has given us His Father as our Father, that through the grace we have received by Him we have come to know God the Father as our own Father, for we stand in Christ as children of God, born again by the Spirit of God through baptism, having become new creatures in Jesus to the hope of everlasting life in the world to come.
Only biological creatures procreate, procreation being part of our intrinsic biology. God, being God, does not procreate--God doesn't have a penis, God doesn't have chromosomes, God doesn't have a body, God is neither male or female. God is God. Angels don't procreate either, because angels are lacking biology, sex, bodies, they don't have penises or vaginas either.
