Here the ‘Christ’ (Mashiyach:the-Anointed or the Consecrated person, etc..) is happy to do the ‘Father’s ‘ (Ab’s: Principal’s Will (YH), Chief’s, etc..), as YH’shua (YH’s salvation) did in fulfilling the prophets (the Principal’s Will), that we may know we can – in the state of ‘Consecration or Anointance’ (in Christ).
Father: אָבʼâb, awb; a primitive word; father, in a literal and immediate, or figurative and remote application:—chief, (fore-) father(-less), × patrimony, principal. Compare names in ‘Abi-‘.
Significance of the Name of the ‘Elohiym of Israel:
YHWH (YH) (the ‘I AM’):
“Moses says: May I say who sent me? He asks for ‘God’s‘ [‘Elohiym’s] name. The Israelites will want to know who has sent me, and ‘God’ [‘Elohiym] replies with a sentence, “Ehyeh asher ehyeh.” This is a first person sentence that can be translated, “I am who I am”, or perhaps, “I will be who I will be,”..

The name that is what the Creator is /does! The Name that calls us to be /do as the ‘Elohiym of Abraham is or does. May it be so in YH’shua.
