All that schooling and you don't even know that YHWH is a name.
Goes to prove that the schools are bias.
You should have studied Aramaic instead of Greek.
Amen.
And as for our heavenly Father, the following passages have been posted and expounded many times. The Father even specifically says that He desires for us to call Him "my Father", in fact, one cannot even be placed among His sons without calling Him Father. I cannot count the times the following passages have been posted not to mention other posts with full commentary:
Deuteronomy 32:1-6
1 Give ear, O heavens, and I will speak; and hear, O earth, the words of my mouth!
2 My doctrine shall drop as the rain, my speech shall distill as the dew, as the small rain upon the tender herb, and as the showers upon the grass:
3 Because I will publish the name of YHWH: ascribe ye greatness unto our Elohim.
4 He is the Rock, His work is perfect: for all His ways are judgment: an El of truth and without iniquity, just and right is He.
5 They have corrupted themselves, their spot is not the spot of His sons: they are a perverse and crooked generation.
6 Do you thus requite YHWH, O foolish and unwise people? is He not your Father that has purchased you? has He not made you and established you?
Isaiah 63:16
16 Doubtless you are our Father, though Abraham be ignorant of us, and Israel acknowledge us not: You, O YHWH, are our Father, our Redeemer; your name is from everlasting.
Isaiah 64:8
8 But now, O YHWH, You are our Father; we are the clay, and you our potter; and we all are the work of you hand.
Jeremiah 3:4
4 Will you not from this time call unto Me, "Abiy, ("my Father"), you are the guide of my youth"?
Jeremiah 3:17-19
17 At that time they shall call Jerusalem the throne of YHWH; and all the nations shall be gathered unto it, to the name of YHWH, to Jerusalem: neither shall they walk any more after the stubbornness of their evil heart.
18 In those days the house of Judah shall walk with the house of Israel, and they shall come together out of the land of the north to the land that I gave for an inheritance unto your fathers.
19 And I said, How shall I place you among the sons, and give you a pleasant land, a goodly heritage of the hosts of the nations? So I said, You shall call Me "Abiy", ("my Father"), and shall not turn away from following Me.
According to the Jeremiah passage the Master would not even have qualified to be the Anointed one if he would not have called our heavenly Father, "my Father" (Abbiy), or Father, (Abba, see also Mark 14:36, Rom 8:15, Gal 4:6).
