Whatever is called by Yahweh's name is His possession and comes under His authority and protection. God wanted His character to be embedded in Jerusalem, in the temple, and in His people. A new name is necessary for those who develop a new character. This is a renewal of the promise of Revelation 2:17. When Jacob’s character was changed the Lord changed his name, for the purpose of a name is to describe the character.

A name is the “locus of qualities” or the “locus around which characterization actually takes place.” A name may also be a means of revealing character. See a for deeper study:

Names carry the past and the future also includes the present (e.g. "Marah"-- due to the fact that it has bitter waters, therefore the element of present appears). In another place, the Lord changed Abram’s name to Abraham, which means “father of many nations,” because He had “made [him] a father of a multitude of nations” (Gen 17:6). The new name expressed the promise that the Lord would manifest in Abraham’s future. Hence we see that names in the Bible could contain a sense of past, present and/or future. [See-- “What’s in a Name: Yahweh in Exodus 3 and the Wider Biblical Context,” Interpretation 33 (1979): 228].

As I said to Dave earlier in this thread-- ["The way people treat you is a statement about who they are as a human being. It is not a statement about you."]-- The Bible affirms that names often reveal the character of the giver, rather than the bearer of the name (for example, Leah naming her children in Gen 29:31–30:19). See, Meir Sternberg, The Poetics of Biblical Narrative: Ideological Literature and the Drama of Reading (Bloomington, Ind.: Indiana University Press, 1985), 330–31.

When Jesus called some a name it was not to insult, shame or to put a person down: e.g.
"serpent", "vipers", "full of dead men bones" "liars", "blind guides", etc. It was a reflection of their heart and character. Jesus knew their inner being. Since many of us, don't know this of each, none of us should be calling anyone, anything, other than the name we have given here in these forums. This the same reason why we're not to judge one another (Matt 7:1-5). Let's remember, "... for the LORD seeth not as man seeth; for man looketh on the outward appearance, but the LORD looketh on the heart" (1 Samuel 16:7 ).

Let's call on the name, Jesus, and one another, brother. Peace and love... CM
