This excerpt is from the New Testament:
"“Look! [...] call him Immanuel, which includes ‘of God and with us.’”
This is perhaps the most internationally valid name of His (and also Emmanuel).
However, other names have rung true to me as good ways to help us know him (and better!).
One such name is Yeshua:
“Yeshua” is the Hebrew name for “Jesus.” The name is associated with “to rescue, to save, or to deliver.” (Yeshua Hamashiach: Who is Yeshua? | Jewish Voice)
I've also read "Yesu" in a Swahili translation of the Holy Bible given to me at a wonderful soup kitchen in Colorado Springs (Marian House Soup Kitchen | Colorado Springs CO | Facebook). (below: JESUS - Translation in Swahili - bab.la)
Another name is "Jesus Cade Renar" from a spiritual community I have ties with since 2018. This one really helps me to feel the "cowboy" side of Him for one. (reference available upon request)
I've heard of other names such as Sananda and as long as such a name is right to you (rings true, etcetera) then I say it's A-OK, and yet we should be very careful regarding this so I recommend trying out these names I already mentioned first (perhaps researching them further additionally).
If we are earnest in yearning to know Christ and pray to Him to know Him, He will guide us to better understand.
This way we could become like the legitimate mystics and saints of our past likely without having to go through their ordeals (speaking from my own experienced, this is true).
In addition to names Christ also has titles or monikers. The word Christ is a derived from the Greek word “Christos" (Rescuer, Deliverer, Enduring One) and we may refer to Him as the Son of God, the Holy Ghost, and the Messiah also.
If we're speaking of Christ with others, we need to be sure to be respectful of they and their experience, even if they (mayhaps unintentionally) misconstrue what happened with dogmatic beliefs to some degree.
A metaphorical story should help to elucidate this:
Three blind men were gathered near and each began to speak of their experience of something in the middle of them.
The first said, "Wow, I feel thick skin and strong muscles."
The second said, "I feel the coarseness of many hairs."
The third said, "I feel smooth ivory."
Then all at once, they laughed at said, "Hello, elephant!"
We may have limited experience of God and even though we may have a rather valid view of God we could always learn something new.
It's important to keep this in mind if conversing about God.
Be curious, be safe!
