you are still ignoring the FACTS of the Old Testament. WHY don't we ever read, where God says, "I am sending My Son", etc, even ONCE? Or the Messenger of the Lord, Who is Jesus Christ, ever say, "My Father"? THIS relationship is NOT ever mentioned in the OT, but is very clear in the NT?
In Luke 1:35, when the angel is speaking to Mary about the Birth of Jesus Christ, says:
"And the angel answered and said unto her, The Holy Ghost shall come upon thee, and the power of the Highest shall overshadow thee: therefore also that holy thing which shall be born of thee
shall be called the Son of God"
Note what it says, "SHALL BE CALLED", which is the Greek, κληθήσεται, in the FUTURE tense! Not IS CALLED.
Again, speaking of the First Coming of Jesus Christ, we read in Hebrews 1:5
For unto which of the angels said he at any time, Thou art my Son, this day have I begotten thee? And again, I
will be to him a Father, and he
shall be to me a Son?
clearly, WILL BE, ἔσομαι, FUTURE tense; SHALL BE, ἔσται, FUTURE tense. WHY?
