How do those who believe the Son is not Almighty God interpret Revelation 2:23? To me, the deity of Christ is seen all throughout Revelation, and for that matter, the Gospels (e.g. John 1:1) and Epistles, and all of Scripture, but for the purposes of the question, how do those who do not believe in the deity of Christ ('that Jesus is God in the flesh') view such passages as Revelation 2:23?


  Revelation 2:18,20-23 ... These things says the Son of God, whose eyes are like a flame of fire, and whose feet are like refined bronze1 ... But I have this against you [i.e. the congregation at Thyatira]: that you put up with that woman Jezebel, who calls herself a prophetess, and teaches [falsely], and misleads my servants, seducing them into  sexual promiscuity and the eating of things sacrifices to idols. And I have given her time that she might repent, but she was unwilling to repent of her sexual sin. Behold, I will cast her onto a bed of sickness, and those that commit adultery with her into great affliction, if they do not repent of their deeds. And her children I will strike with death; then will all the churches know that I am he  who searches the minds and the hearts, and [that] I render to each of you according to your works.


In light of this being the perogative of YHVH, God Almighty:


  Jeremiah 17:10 I, YHVH, search the heart and examine the mind, to render to each according to his conduct—according to the fruit of his doings.2




IMPORTANT EDIT

As noted by another user 2 Chronicles 6:30 (cf. 1 Kings 8:39) teaches explicitly that YHVH alone knows the hearts of men:


  1 Chronicles 6:14, 30 O YHVH, God of Israel, ... So then, hear from heaven, your dwelling place, and forgive, and render to each one according to all his ways, [you] who know his heart: for you alone know the hearts of the sons of men.

Jehovah's Witnesses have not published an article specifically explaining this verse within the context of the Trinity, but the fundamental argument being presented is a common one: God's actions and Jesus' actions are the same, so they must be the same.
The Bible describes the relationship between God and His Son in great detail, and from this Jehovah's Witnesses believe that Jesus is not God, but that he imitates his Father and is given authority by his Father. For example, when the Jews were accusing Jesus of &quot;making himself equal to God,&quot; Jesus responded by saying:

John 5:19-24
“Most truly I say to you, the Son cannot do a single thing of his own initiative, but only what he sees the Father doing. For whatever things that One does, these things the Son does also in like manner. For the Father has affection for the Son and shows him all the things he himself does, and he will show him works greater than these, so that you may marvel. For just as the Father raises the dead up and makes them alive, so the Son also makes alive whomever he wants to. For the Father judges no one at all, but he has entrusted all the judging to the Son, so that all may honor the Son just as they honor the Father. Whoever does not honor the Son does not honor the Father who sent him. Most truly I say to you, whoever hears my word and believes the One who sent me has everlasting life, and he does not come into judgment but has passed over from death to life.

This verse shows that Jesus has been given the authority to judge and that Jesus acts like God, not because he is God, but because he sees God and imitates him. Jesus gave the ultimate example of how the rest of God's children should also imitate God.—Ephesians 5:1, 2.
There are many other verses which also describe how Jesus was given authority. Daniel spoke of it prophetically, and Jesus and Paul both attest to how it came true.

Daniel 7:13, 14
“I kept watching in the visions of the night, and look! with the clouds of the heavens, someone like a son of man was coming; and he gained access to the Ancient of Days, and they brought him up close before that One. And to him there were given rulership, honor, and a kingdom, that the peoples, nations, and language groups should all serve him. His rulership is an everlasting rulership that will not pass away, and his kingdom will not be destroyed.



Matthew 28:18
Jesus approached and spoke to them, saying: “All authority has been given me in heaven and on the earth.



Philippians 2:9-11
For this very reason, God exalted him to a superior position and kindly gave him the name that is above every other name, so that in the name of Jesus every knee should bend—of those in heaven and those on earth and those under the ground— and every tongue should openly acknowledge that Jesus Christ is Lord to the glory of God the Father.

Therefore, Jesus has the authority and power to be the Judge of peoples' minds and hearts because God commissioned him with that responsibility. Prior to that, however, God dealt with Israel alone, functioning as the only reader of hearts in the Hebrew Scriptures. Some verses refer to Jesus as &quot;the arm of Jehovah&quot; because he accomplishes God's will.—Isaiah 40:10; 53:1; John 12:37, 38.
