Let's do a mini-study of John 5:18...

John 5: 18. And because of this the Yehudeans were seeking all the more to kill him, not only because he had loosed[1]  the Shabbat, but also concerning that he would say that his Father was Elohim and was equating[2]  himself with Elohim. (AENT)

NOTES:

[1]  Y’shua did not break the Shabbat according to Torah; rather, he restored the observance of Shabbat as YHWH intended, without the burden of religious tradition.  In so doing, the traditions of the Pharisees had been violated, but certainly NOT YHWH’s Torah, whose every word was written down by Moshe, as instructed.
  
[2]  To consider oneself “equal” to YHWH is a very serious matter!  Y’shua spoke of himself as being about his Father’s business, of coming in his Father’s Name; he spoke and taught with authority and performed healings which made him a formidable opponent to religious tradition. 

The charge here of Y’shua making himself equal to YHWH is simply Pharisee tradition projecting itself onto Y’shua.  The Ruach haKodesh (Holy Spirit) in Mashiyach (Messiah) is “equal” to YHWH, but the Pharisees supposed that Y’shua and his followers equated his humanity with YHWH. 

They didn’t understand Isaiah 11:1-2, that Mashiyach has the Ruach haKodesh/Holy Spirit (which is another name for YHWH — Psalm 51:1-11, Isaiah 63:1-11) within him.  YHWH spoke through the Spirit of Mashiyach, rather than through his human component! 

Remember, in Torah YHWH said HE would send a prophet who was to do everything He ordered him to do:

Deuteronomy 18: 15 "ADONAI will raise up for you a prophet like me from among yourselves, from your own kinsmen. You are to pay attention to him, 16 just as when you were assembled at Horev and requested ADONAI your God, 'Don't let me hear the voice of ADONAI my God any more, or let me see this great fire ever again; if I do, I will die!' 17 On that occasion ADONAI said to me, 'They are right in what they are saying. 18 I will raise up for them a prophet like you from among their kinsmen. I will put my words in his mouth, and he will tell them everything I order him. (CJB)

Yeshua Himself said He came to do HIS FATHER's will; not his own!

John 6: 35. Y'shua said to them, I am the Bread of Life. Whoever comes to me will not hunger. And whoever believes in me will not ever thirst. 36. But I have said to you that you have seen me, and you do not believe. 37. All who my Father has given to me will come, and whoever comes not to me I will cast outside!

38. For I came down from heaven, not to do my will, but to do the will of Him who sent me. 39. And this is His will, that of Him who sent me, that all that He has given to me I do not lose even one. 40. For this is the will of my Father, that all who see the Son and believe in him, will have life that is eternal. And I will raise him up on the last day. (AENT)

NOTE: As in the context of Miltha (the Word) or the "Manifestation" or the "Will of" YHWH coming down from heaven to do the Will of YHWH upon earth; his Spirit is of YHWH but his nephesh (soul) and body are human and temporal. This shows that Yeshua was NOT in charge at the time; HIS FATHER WAS!  (YHWH Himself cannot be born or die; but his human Messiah did both.)

Y’shua maintained that his nefesh (soul) would die, but that YHWH would resurrect it! Y’shua believed his own nefesh was mortal.  Zechariah 12:10 the Spirit of YHWH is “pierced” but they mourn for him (Y’shua) as an only begotten son.  YHWH Himself cannot literally be “pierced”; therefore, this refers to Mashiyach who has the Spirit of YHWH in him.
