4 But when the right time came, God sent his Son, born of a woman, subject to the law.
5 God sent him to buy freedom for us who were slaves to the law,
so that he could adopt us as his very own children.
6 And because we are his children,
God has sent the Spirit of his Son into our hearts,
prompting us to call out, "Abba, Father."
7 Now you are no longer a slave but God's own child.
And since you are his child, God has made you his heir.
“Abba” is for Jews the intimate name used for the father – possibly like “papa”.
Using it means a person is addressing someone with whom they have a very very close, familiar, intimate, open relationship.
That is the term Paul says we can use with the God of the universes who is eternal, who ever has been & ever will be.
Paul maintains that we a followers of Jesus have been adopted into God's family – iow, God considers us His children.
This is another indicator of the level of connect God now has instigated between us & Him.
The God of the universes, who is so unspeakably holy, who knows everything, who is completely all powerful & wise, who is the very essence of love, who is, always has been, & always will be, considers us to be His children.
This was an astounding piece of information to everyone & anyone of Paul's time – no God said He thought of His creation as His children.
It is still something people consider astounding when they discover it.
And if we are His children, then everything God has is ours.
If you want to short circuit your brain, try to wrap it around the fact that God simply “is” - He ALWAYS has been around, & He ALWAYS will be around.
Then if your brains isn't completely fried, then consider that we, as God's children, are now on the eternal continuum with Him – and as His children, have access to everything He is, & everything He has.
This may be a bit much too much – think about it today during some down time today – like during the sermon today at church ( ;-) LOL )
