History on the Letter J
The letter J originated as a swash character to end some Roman numerals in place of i. The letter J came about in the 17th century where it was established as a constonent.
A distinctive usage emerged in Middle High German. Gian Giorgio Trissino (1478–1550) was the first to explicitly distinguish I and J as representing separate sounds, in his Ɛpistola del Trissino de le lettere nuωvamente aggiunte ne la lingua italiana ("Trissino's epistle about the letters recently added in the Italian language") of 1524.
 Originally, both I and J repesented /i/, /iː/, and /j/; but Romance languages developed new sounds (from former /j/ and /ɡ/) that came to be represented as I and J; therefore, English J, acquired from the French J, has a sound value quite different from /j/ (which represents the sound in the English word "yet").

IS THE MESSIAH NAME JESUS?
When the Messiah walked the earth over 2000 years ago the name Jesus was not in Existence. The Messiah was a Hebrew Israelite from the Tribe of Judah, He lived as a Hebrew with a Hebrew Name given to him from Yah the father. The name Jesus is English, there is no J or J equivalent in the Hebrew language. Jesus is not the English translation of the Messiah's Hebrew name. Jesus is a name created by men not by the Most High. The Hebrew Messiah name is Yahshuah, which means Yah's Salvation or Salvation of Yah, his name tells you whom he is and what his mission is. He is Salvation, the very belief on his true name can get you salvation.
Acts 4:12 Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved.
John 2:23 Now when he was in Jerusalem at the Passover, in the feast day, many believed in his name, when they saw the miracles which he did.
John 20:31 But these are written, that ye might believe that Yahshuah is the Messiah, the Son of Yah; and that believing ye might have life through his name.
John 1:12 But as many as received him, to them gave he power to become the sons of Yah, even to them that believe on his name:
Acts 3:16 And his name through faith in his name hath made this man strong, whom ye see and know: yea, the faith which is by him hath given him this perfect soundness in the presence of you all.
Acts 10:43 To him give all the prophets witness, that through his name whosoever believeth in him shall receive remission of sins.
The name of the Messiah is very important you can't get around it. You have to call upon him by his Yah given Hebrew name, as it states in Acts 4:12 no other name can be a substitute, no translation of his name. Only his true name given from Heaven which can be spoken in every language, is your key to salvation. There is no need for a translation. You really need to get our audio lesson entitled "THE TRUE MESSIAH REVEALED" We go into details from scripture to fully explain the MISSION, NAME, IMAGE, AND TRUTH OF THE MESSIAH.

Even though Jesus is in the KJV doesn't mean it is not a mistranslation, the name Jesus did not appear in the original 1611 KJV because the letter J was not in wide spread use yet. Many of the newer bibles have corrected that mistake. Some such as "THE SCRIPTURES" use the messiah true Hebrew Name Yahshuah.
Now Ask Yourself how can Jesus be the True name when it didn't Exist until 15-17 centuries after the Messiah earthly mission. As I stated, the Name Jesus was not in existence during ancient times and it wasn't in existence at the translation of the KJV.
