You didn't answer my question. Do you believe we are sinning when we use the word Jesus for Messiah?
What I believe has no bearing on your relationship with our heavenly Father. That is between you and our heavenly Father. As you understand Yahshua proclaims Yah's salvation for us.
YesheYahu (Isa) 43:
11 I, even I, am YHWH; and beside Me there is no savior
Yahshua brings glory to YHWH. We are called to follow Yahshua's example.
John 17:1-9
17:1 After Yahshua said this, he looked toward heaven and prayed: “Father, the time has come. Glorify your Son, that your Son may glorify you. 2 For you granted him authority over all people that he might give eternal life to all those you have given him. 3 Now this is eternal life: that they may know you, the only true God, and Yahshua Messiah, whom you have sent. 4 I have brought you glory on earth by completing the work you gave me to do. 5 And now, Father, glorify me in your presence with the glory I had with you before the world began. 6 “I have revealed you to those whom you gave me out of the world. They were yours; you gave them to me and they have obeyed your word. 7 Now they know that everything you have given me comes from you. 8 For I gave them the words you gave me and they accepted them. They knew with certainty that I came from you, and they believed that you sent me.
Yahshua came in his heavenly Father's name.
(CLV) Jn 5:43
I have come in the name of My Father, and you are not getting Me. If another should be coming in his own name, him you will get.
Yahshua's name was given by YHWH. Yahshua's name has meaning.
Matt 1:20-21
20 But after he had considered this, an angel of Yahweh appeared to him in a dream and said, “Joseph son of David, do not be afraid to take Mary home as your wife, because what is conceived in her is from the Holy Spirit. 21 She will give birth to a son, and you are to give him the name Yahshua, because he will save his people from their sins.
Acts 4:12
12 Salvation is found in no one else, for there is no other name under heaven given to men by which we must be saved.”
I choose to give our heavenly Father all of the glory he deserves.
