Yayshua is Hebrew for Jesus (sometimes spelled Yeshua, Yahshua, Y'shua, Yehoshua, Yaohushua, or Yahushua).  Yayshua is the way the standard Hebrew is pronounced.   Yayshua is the first and the last (Rev. 1:17).   He said, "If you do not faithfully trust that I am He, you will die in your sins" (John 7:24; Isaiah 41:4).  For this reason, we emphasize  the full deity of Yeshua.  You can find our doctrinal statements at our site, which also outline other important truths.
