"Who is the image of the invisible God, the firstborn of every creature
Colossians 1:15 -- King James Version)
"He is the image of the invisible God, the firstborn of all creation."(Colossians 1:15 -- New American Standard Bible)
You are misusing the term "firstborn" concerning it's usage in scripture.
Here are some examples from the NWT:
Psalm 89
20
I have found David my servant;
With my holy oil I have anointed him,
21With whom my own hand will be firm,
Whom my own arm also will strengthen.
22No enemy will make exactions upon him,
Neither will any son of unrighteousness afflict him.
23And from before him I crushed his adversaries to pieces,
And to those intensely hating him I kept dealing out blows.
24And my faithfulness and my loving‐kindness are with him,
And in my name his horn is exalted.
25And on the sea I have put his hand
And on the rivers his right hand.
26He himself calls out to me, ‘You are my Father,
My God and the Rock of my salvation.’
27Also,
I myself shall place him as firstborn,
The most high of the kings of the earth.
Was David the first child of his parents? No.
1 Samuel 16:11
Finally Samuel said to Jes′se
: “Are these all the boys?” To this he said: “
The youngest one has till now been left out, and, look! he is pasturing the sheep.” At that Samuel said to Jes′se: “Do send and fetch him, because we shall not sit down to meal until his coming here.”
Here's another, Ephraim:
Jeremiah 31:9
With weeping they will come, and with [their] entreaties for favor I shall bring them. I shall make them walk to torrent valleys of water, in a right way in which they will not be caused to stumble. For I have become to Israel a Father; and as for E′phra‧im,
he is my firstborn.”
Is Ephraim the first child that was sired? No.
Genesis 41:50-52
And before the year of the famine arrived there were
born to Joseph two sons, whom As′e‧nath the daughter of Pot‧i′phe‧ra the priest of On bore to him.51So Joseph called the name of the
firstborn Ma‧nas′seh, because, to quote him, “God has made me forget all my trouble and all the house of my father.”52And the name of the second he called E′phra‧im, because, to quote him, “God has made me fruitful in the land of my wretchedness.”
In fact, in Genesis 41 it describes Josephs first son as being Manaseh.
You are misusing the word "Begotten". You are taking a modern definition and placing it into a word that was not used with the modern definition in mind back in 1611. The usage of the word Begotten has continued to be used as a tradition of translation (using familiar phrases).
If you are going to argue that Jesus is the "only begotten" Son of God in the sense that "he is the only Son God has made for himself", then you are going to have to deny that Abraham had more than one son.
Here's why.
From the NWT.
Hebrews 11:17-19
By faith Abraham, when he was tested, as good as offered up Isaac, and the man that had gladly received the promises attempted to offer up [his]
only‐begotten [son],18although it had been said to him: “What will be called ‘your seed’ will be through Isaac.”19But he reckoned that God was able to raise him up even from the dead; and from there he did receive him also in an illustrative way.
Galatians 4:22 from the NWT
For example, it is written that Abraham
acquired two sons, one by the servant girl and one by the free woman
Abraham sired two sons.
QUESTION #4 to JIMMY DIGGS: According to Colossians 1:15 and John 1:14, did Jesus exist for eternity or was he created?
Jesus existed for eternity.
QUESTION #5 to JIMMY DIGGS: An eternal person cannot die. Didn't Jesus Christ literally die?
Yes, he died, but he did not cease to exist as a being.
Then he was physically raised:
From the NWT:
John 20
Well, eight days later his disciples were again indoors, and Thomas with them. Jesus came, although the doors were locked, and he stood in their midst and said: “May ​YOU​ have peace.”27Next he said to Thomas: “
Put your finger here, and see my hands, and take your hand and stick it into my side, and stop being unbelieving but become believing.”28In answer Thomas said to him: “
My Lord and my God!”29Jesus said to him: “Because you have seen me have you believed? Happy are those who do not see and yet believe.”
Then Thomas declares Jesus to be his Lord, and his God.
