Featured I and the Father are one

Matthew 10:40
“He who receives you receives Me, and he who receives Me receives Him who sent Me.

Mar 9:37
“Whoever receives one child like this in My name receives Me; and whoever receives Me does not receive Me, but Him who sent Me.”

Thus the Father sent the Son, so the Son was operating in subordination to the Father.

Luke 4:18
“THE SPIRIT OF THE LORD IS UPON ME,
BECAUSE HE ANOINTED ME TO PREACH THE GOSPEL TO THE POOR.
HE HAS SENT ME TO PROCLAIM RELEASE TO THE CAPTIVES,
AND RECOVERY OF SIGHT TO THE BLIND,
TO SET FREE THOSE WHO ARE OPPRESSED,

And here we see that the Father "anointed" the Son, again showing subordination.

John 4:34
Jesus *said to them, “My food is to do the will of Him who sent Me and to accomplish His work.

Again and again scripture clearly teaches Christ was subordinate to the Father while incarnate. But other verses teach God the Son takes direction from the Father even before the incarnation.

Here is an example of pre-incarnate subordination.

John 6:38
“For I have come down from heaven, not to do My own will, but the will of Him who sent Me.

The pre-incarnate God the Son took the God the Father's direction before the incarnation.

Hebrews 1:2
In these last days has spoken to us in His Son, whom He appointed heir of all things, through whom also He made the world.

Here we see God the Father spoke to us "in His Son," and that God the Father "appointed" His Son heir of all things," and that God the Father made the world (humankind) through or by means of His Son. And note the subordination involved with the making of the world occurred before the incarnation.
