MOSES IS ALREADY ACCUSING YOU Jn. 5:39

John 5:45 (GW)
45 “Don’t think that I will accuse you in the presence of the Father. Moses, the one you trust, is already accusing you.

The grammar fits looking for w word that reflects present time  usually ending in “ing”‘

Other translations say your accuser is Moses. the present day ongoing effect will haveeffect to everyne whoever will not listen to  the words God has put in his mouth, and we see that confirmed in ohn chapter 5 when he says Initiated when Moses prophesied the statement was set up when Moses spoke those words in the wilderness in Dt 18:15,18,19 .

I will put My words in his mouth, and he shall speak to them all that I command him.
‘”it shall come about that whoever will not listen to My words which he shall speak in My name, I Myself will require it of him.”
those very words were spoken by Moses containing a prophecy about Jesus and warning to those who would ignore them  Jesus ha already he seeks ONLY  the will of  the Father John 5:30 .
