Recently I read a thread about God's name. So I did some research on the word "name" in the bible. What I came away with is the question, "Does God change?". The bible says that Abram's name was changed to "Abraham" by God after a certain change in him. Names in those days had meaning. Lots of people and places in the bible were named for significant events or changes which took place. When the background or history of those people and places changed, so did the name.
Abraham was said to have preached "in the name of Jehovah" (Gen. 13:4). But was God's name Jehovah at that time? No.
And God saith again unto Moses, `Thus dost thou say unto the sons of Israel, Jehovah, God of your fathers, God of Abraham, God of Isaac, and God of Jacob, hath sent me unto you; this [is] My name -- to the age, and this My memorial, to generation -- generation.
and I appear unto Abraham, unto Isaac, and unto Jacob, as God Almighty; as to My name Jehovah, I have not been known to them;
(Young's literal translation)
What was God's name before Moses asked? Does it matter? The important point is His name CHANGED. Because of a significant event, God took on a new name. That name means "I will be what I will be". Seems to me that God was saying, "I've named people and places all over this land and I'll call myself whatever I damn well please, whenever I please." CHANGE.
What about Jesus? Born into the Jewish faith, did he just go along with the crowd and follow the religious leaders? No, Jesus was all about change!
God can call Himself anything He wants anytime He wants, so yes, it seems to me He does change.
