According to the Old Testament Jesus (peace be upon him) cannot be a saviour.
According to Christian belief Jesus is a prince. He is the prince of peace. In the New Testament we read again and again that Jesus is called ‘the Son of Man’. In fact, that expression is mentioned for Jesus over 83 times throughout the New Testament. Consider the following verse, ☛ “Put not your trust in princes, nor in the son of man in whom there is no help.” (Psalms 146:3) Interestingly enough the word help in the above verse is 'shua' in Hebrew. Do you recall the name of Jesus in Hebrew? It’s Yeshua which is rendered “God saves”. Christians often use this as proof that Jesus himself is God who saves. This would be like saying that Hezekiah is God because his name means ‘Strong God’ or Ishmael which means ‘God hears’. Surely, they do not mean anything more than reflections of God Himself and not those who bear those names. The names act as a way to remind the people regarding God. Yeshua cannot possibly be calling Jesus God who saves in light of Psalms 146:3 which clearly disqualifies him as one who offers 'shua' or salvation. Jesus himself is no more than a messenger appointed by God (John 17:3). We have yet another verse that undermines the notion that Jesus is the source of salvation, ☛ “It is better to take refuge in the LORD Than to trust in man.” (Psalms 118:8) The same message is found in Psalms 108:12 and Psalm 60:11, ☛ “Oh give us help against the adversary, For deliverance by man is in vain.” Was Jesus not a man?.
