We can be sure that John was writing to the Jews, the caretakers of the word of God, the law and the prophets that all looked toward the coming Christ and the unfolding and re-envisioned Holy Days that found their true meaning through the New Covenant and its convenor Jesus through his blood, death and new life as the firstborn from the dead, Col 1.
So we can either follow a Greek or a Hebrew take on John’s prologue. A Greek slant would have a philosophical base, the Hebrew a deep rooted foundation in the previous millennia’s teaching.
Why would we entertain a Greek interpretation when it has no connection with the past. God does nothing that becomes redundant, but is a taste, a shadow of something much grander that was always in His mind, but hidden until the time was right/according to plan.
His teaching in Isaiah then is crucial to understanding the new covenant and the teaching of the NT- especially the core of the plan, the re-envisioned word!
It doesn’t take much imagination to realise that what God wants, God eventually gets. He is so sovereignly
above our pay grade, He can arrange the past, present and future to achieve a divinely conceived outcome.
...my word be that goes out from my mouth; it shall not return to me empty, but it shall accomplish that which I purpose...
This concept is the foundation for the whole OT. The characters that lived out the stories like David, Joseph, Moses etc, are proof enough that God gets His way, in spite of the opposing forces that might think themselves formidable - like Pharaoh and his army and his pathetic gods.
Why abandon this foundation for another philosophical approach that has no connection with all that has gone before?
John 1 continues this foundation with a new aspect to this ‘word of God’. No longer is it just a word, a decree, a plan, a will of God - it is the same, but now it is a man! Not a dumb robotic man, but a man with his own will who must constantly choose the right words, actions, and decisions. Decisions that would lead unswervingly to his hideous death on a cross!
For brevity, I will leave out explaining unswervingly.
So yes, the word in Isaiah 55 is perfectly analogous with the word in John. It is still God’s word, still His will and purpose, but now in fleshly human form who must function within the spiritual realm opposing evil, not by unalterable decree, but by loving and trusting choice of humility not pride, obedience not resistance.
Notice the parallels with Isaiah 55:6--11 and the words of Jesus, the new Lord.
Seek the LORD while He may be found;
Call upon Him while He is near.
7 Let the wicked abandon his way,
And the unrighteous person his thoughts;
And let him return to the LORD,
And He will have compassion on him,
And to our God,
For He will abundantly pardon.
11 So will My word be which goes out of My mouth;
It will not return to Me empty,
Without accomplishing what I desire,
And without succeeding in the purpose for which I sent it.
Walk while you have the light, before darkness overtakes you. John 12:35
The time has come," he said. "The kingdom of God has come near. Repent and believe the good news!" Mk 1:15
believe in the Lord Jesus, and you will be saved--you and your household." Acts 16:31
1 John 1:1 perfectly explains this logos, which was made manifest in God’s son, Jesus. Further, in this passage, John refrains from confusing the logos and Jesus but carefully linking them appropriately.
