There are many titles to God such as Lord, God, Almighty, and Father. However, the name of Almighty God, the Creator, is clearly and simply stated at Psalm 83:18: “That men may know that thou, whose name alone is JEHOVAH, art the most high over all the earth.” (King James Version)
Isaiah 42:8 "I am Jehovah. That is my name.."
God's name is Jehovah in English. Yehova in Swahili. Yehowa in Ga. Jexoba in Macedonian. The point is God doesn't have multiple names, but different cultures pronounce his one name differently.

But if you try to get in touch with Him, He frequently responds to "Help."
