Diagnosed, thanks for the compliment; glad to know someone reads and appreciates my efforts here.
Tobakki3, I am not qualified or interested in detailing the 100+ names assigned to God, but I can answer your question by addressing the most common ones used in English.
YHWH is the proper Hebew name for God given to the Israelites. As a tetragrammaton (having no written vowels), it's often pronounced Yahweh or Yehowah, though no certainty exists for what actual vowels were pronounced by the ancient Hebrews. LORD is the accepted English translation of this proper name, while Jehovah is a questionable translation popularized by the King James Bible and Jehovah's Witnesses. Jehovah is a German pronunciation of the Latin transliteration of YHWH. The vast majority of Jewish and Christian biblical scholars and linguists do not believe Jehovah is the proper pronunciation of YHWH - first because there is no true J sound in ancient Hebrew, and second because the Hebrew letter vav, which is transliterated as the W in YHWH, originally had a pronunciation closer to W rather than the V of Jehovah. “Yahweh” or “Yehowah” is far more likely to be the correct pronunciation. In any case, the tetragrammaton's root meaning is "I AM" and suggests eternal self-existance. Be it YHWH, LORD, or Jehovah, this name is used over 6800 times in the Old Testament - the most frequent of all names.
Elohim is a Hebrew word that denotes “God” or “god.” It is the second most frequent name for God in the Old Testament, being used over 2250 times. The basic meaning behind this name is one of strength or power. Elohim is the infinite, all-powerful God who shows by His works that He is the creator, sustainer, and supreme judge of the world. Interestingly, the Hebrew suffix "im" indicates that the word Elohim is grammatically plural. While this may be interpreted as a way of emphasizing greatness, power, and prestige, it's also consistent with the Bible's overall teachings of his triune nature (1 god in 3 persons).
Your second question/comment Tobakki3 suggesting that God suddenly decided to make a child and call him Jesus also deserves a response. Anyone with a receptive heart and some research can easily surmise that the Old Testament references a future suffering servant or Messiah that would intervene between God and man. From Genesis and Psalms through the prophets of Isaiah, Zechariah, Micah, and others, over 300 of these prophesies exist and no one but Jesus has fulfilled them. A mature understanding of the Bible is recognizing that Jesus is interwoven throughout God's plan of creation, man's downfall, and the redemption of our relationship with God. To anyone who recognizes the Bible's authority as being true, it is clear that Jesus has existed eternally, and his incarnation onto earth as a man 2000 years ago can hardly be considered a sudden, new idea or change of plans. This of course is a key doctrine of Christianity, accepting that Jesus was not a mere prophet or teacher that lived on earth for 33 years, but God himself visiting his Creation in human form. Virtually all other religions in the world reject this premise, but they can't legitimately discredit the numerous, specific Old Testament prophesies he fulfilled.
SpiffyPanda, I apologize if I've misinterpreted you, but your summation of all religions sounds like the popular notion these days of placing relative truth over objective truth. If so, I'd suggest that your own conclusions are self refuting. In other words, your accusation that there is no objective truth discredits your stated beliefs, since they themselves can't be trusted to be truthful.
Consider, in a world with no objective morality, one culture can justify sacrificing innocent children to their god, enslaving the weaker people, killing the less attractive or unproductive members of society, raping women freely on the streets, or torturing and mutilating little babies for a spectator sport. Can I assume then that you'd hold no objective moral standard to this type of society? After all, if they think its ok for them, who are you to say otherwise? Hmmm. Might I suggest that, just as the universe holds to scientific objective truths that reflect reality, so are certain moral values innate within our hearts. These values cross cultural boundaries and individuals, meaning that certain things are intrinsically wrong whether the country or individual recognizes (and respects) it or not. If we're just animals originating from chance chemical processes, such consciousness of moral values is illogical. But, if we're created in the image of God, who has a mind and a conscience, then it makes sense that we would inherit his sense of moral values and recognize his establishment of objective truth. That being the case, the true God who created us and this universe isn't about to change his truths to accommodate our ever changing cultures and moral values. No, once you recognize that there is a supreme creator and ruler of the universe, you must realize too that his nature and laws are THE objective standard. After all, he who makes the universe gets to make the rules. Each person must decide for themselves which religion accurately represents the true creator and god of the universe. If you want a man-made religion that changes with the times, you've plenty of choices, including new religions being popularized each century. But the one true religion of Christianity depends upon the Holy Bible's scriptures, which represent the words of God himself. You're free to accept or reject their truths, but don't expect God to change them for us.
