The phrase "firstborn of all creation" is not dealing with time.
At (
Psalm 89:20-27). God states, “I have found David My servant. With My holy oil I have anointed him…
I also shall make him My firstborn, the highest of the kings of the earth, David was not the firstborn of his family. In fact, he was the
last one born. David is called the firstborn, "the highest of the kings of the earth." Firstborn is a title of preeminence. Jesus is the highest of the kings of the earth.
At
Genesis 41:51-52 it says, "And Joseph called the name of the
first-born Manasseh … And
the name of the second called he Ephraim At
Jeremiah 31:9 it states, " . . . for I am a father to Israel, and
Ephraim is My firstborn,"
Note that the firstborn title was transferred from Manasseh to Ephraim the second one born. You can clearly see that the term "firstborn" does not necessitate the first one created or the first one born.
At Revelation 1:5 it states, … and from Jesus Christ, the faithful witness, the
firstborn of the dead, and the ruler of the kings of the earth.
Isaiah 9:6 foretells the firstborn to come, "For a child has been born to us, A son has been given to us; And the rulership will rest on his shoulder. His name will be called Wonderful Counselor,
Mighty God,
Eternal Father, Prince of Peace,"
Look at the title
Mighty God. The adjective being used is Mighty. At Isaiah 10: 21 it says … remnant will return, the remnant of Jacob, to the
mighty God. Jeremiah 32:18 pronounces: … O great and
mighty God. And Zephaniah lauds in similar terms: "The Lord your God is in your midst, a
mighty one" (
Zephaniah 3:17). Who is this
mighty one? The answer is in Isaiah 9:6 and notice that he is also called "
Eternal Father"
So this firstborn son, the image of God, is also the Mighty God and Eternal Father. This all makes sense when you put everything together and take everything in context.
