They all have one or more deities to whom they worship. There is only one true God if you are Christian. His name at Psalm 83:18 is Jehovah. Some pronounce it Yahweh. The Hebrews used to write his name YHWH they didn’t use vowels. So they aren’t sure how to procounce. Jesus’ name was Yeshua but pronounced Jesus in English.
The impliccations of knowing Gods name is Rom 10:13 at Armageddon they will be saved.
God is energy. God is the sum total of our habits, behaviors, reactions, beliefs, actions. Even down to our perception. If we think of the human body as a vessel “temple” if our temple is full of anger, hate, resentment etc .. God cannot express through a temple that hold such a state of being. Energy or God can only express through a channel that is of a higher nature. That would be whomever’s personality, character and likeness is closest to Gods.

It’s fascinating how different religions have various interpretations of the divine. Understanding the significance of God’s name, whether it’s Jehovah, Yahweh, or YHWH, adds depth to our spiritual journey. The promise of salvation, as mentioned in Romans 10:13, underscores the importance of this knowledge in Christian belief.
