Who is Yeshua?
Yeshua is the name of G-d the Son. Some may say no it is not, his name is Jesus! Unfortunately, the naysayers have not been taught correctly. It is not a sin to call the Son, Jesus. However, if we lived during "Jesus" time on Earth people would not have called him Jesus, but Yeshua. You may ask, "Why?' The answer is His parents named Him Yeshua, not Jesus. Also, the name Yeshua translates in Hebrew as "Salvation". His name in Hebrew is sometimes Yahoshua which translates, "Lord who is Salvation." The name Yahoshua is also the translated "Joshua". Jesus is a loose interpretation of the name Joshua and has no meaning. The name Jesus was also a mis-translation of Greek. Why then would anyone educated with the facts want to call the Lord by a name that is not purely His? When you are calling on the Lord it is important to call on a name with meaning and "Salvation."
Q: This may bring about the question, "Can you still cast out demons in the name of Jesus?"
A: I believe a demon can be cast out, binded or healing can take place in the name of Jesus because principalities, as well as Yeshua, comprehend the attributes to the name Jesus. Also understand that G-d is omniscient, that is all knowing, so He knows.
