What does that have to do with the Name Jehovah ? But
When Jesus prayed he used Father, My Lord and my God, never by name Jehovah
Would queen Elizabeth find it odd if her husband said Hello Elizabeth
This is appropriate for the fact they are husband and wife, now regard her children they would never call her Elizabeth.
Sorry, I was not clear. Yes, Lord, God and Father, but in Jesus model prayer [Matt 6v9 and Luke 11v2] doesn't Jesus pray that 'his Father's name' should be hallowed? How can one 'hallow', ' make sacred', 'sanctify' God's name ?
Yes, Elizabeth's son would not say Elizabeth instead of mother.
Would you consider Jeremiah as a son of God ?
Jeremiah [31v3] in the Hebrew used Jehovah [YHWH] instead of LORD.
Jehovah said to Jeremiah.
Would you consider Isaiah as a son of God ?
Isaiah [31v4] mentions Jehovah [YHWH] speaking to Isaiah.
See also Isaiah chapter 12 KJV.
Would you consider David as a son of God?
David's Psalm [68vs4,11] mentions by his name 'Jah' and Jehovah
Would you consider John as a son of God?
at John [12v13] doesn't John write blessed is Jesus who comes in the name of Jehovah [YHWH] ? John did not write: comes in his own name Jesus, but comes in God's name. See also Mark 11v9; Matthew 23v39 and Luke 13v35.
No Bible writer refrained from using the Tetragrammaton [YHWH]
Jesus too was unique in that Jesus is the Son with a capital 'S'.
Jesus was a heavenly direct creation according to Revelation 3v14.
So, like Elizabeth's son would properly address her as mother,
Jesus as a directly created Son would address his God as Father.
-Rev 3v12.
That does not mean God's name should be avoided.
If Elizabeth's son was writing a letter to someone would he necessarily avoid using her name? Might not he say 'my mother Elizabeth', or 'my mother's name is Elizabeth' ? Since Elizabeth's son could properly write and say his mother's name, and even fill in her name on question forms, then why couldn't or shouldn't Jesus ?
