Moses says in Exod. 3:14-15 that Jehovah told him that His name means: "I AM THAT I AM." Hebrew students say that the original word is JHVH. which means the ever living male-and-female principle. Lee's Hebrew Lexicon identifies this name with Christ, as the manifestation of God that speaks to patriarchs and prophets. Jesus confirms this in Matt. 22:42-45, where He reveals that the Christ existed before David, whose son He was supposed to be. In the Old Testament the spiritual I AM is symbolically described as Jehovah- in the New Testament it is called Christ.
Creation originates and exists in Divine Mind, God. In the creative process Divine Mind first ideates itself. In the Scripture this ideal is named Jehovah, meaning I AM the ever living--He who is eternal. The creation is carried forward through the activity of the Holy Spirit.
The Hebrew Jehovah has been translated "Lord." Lord means an external ruler. Bible students say that Jehovah means the self-existent One. Then instead of reading "Lord" we should read I AM. It makes a great difference whether we think that I AM, self-existence, is within, or Lord, master, without. All Scripture shows that Jehovah means just what God told Moses it meant, I AM. "This is my name forever, and this is my memorial unto all generations." So whenever you read the word Lord in Scripture say I AM instead and you will get a clearer understanding of what Jehovah is. Jehovah-jireh means I AM the provider. If we expect to demonstrate prosperity from without we find it a slow process; but if we know that I AM is the provider we have the key to the inexhaustible resource. God was also known to the Israelites as Jehovah-shalom--"I AM peace." We can demonstrate peace of mind by holding the words, "I am peace." with the understanding that the real I AM is Jehovah within us.
