Moreover God said to Moses, “Thus you shall say to the children of Israel: ‘The LORD God of your fathers, the God of Abraham, the God of Isaac, and the God of Jacob, has sent me to you. This is My name forever, and this is My memorial to all generations.’” (Exodus 3:15)
The Hebrew word that is translated “LORD” in this verse isn’t actually a word but a name formed by the letters yod, hei, vav and hei. In times past it has been transliterated as Jehovah, Yahweh and, sometimes, just YHVH. What’s important is that this is understood to be God’s sacred name, so sacred in fact, that Jews are hesitant to try and pronounce it, preferring to refer to God as HaShem (literally, “the Name”).
This Hebrew spelling comes from the same Hebrew root as ehyeh (“I Am”) which is hayah, meaning “to be.” Thus the name YHVH expresses His eternal attribute — that He was, He is and He will forever be and all at the same time. In other words, the LORD transcends time. He is not limited by our concept of time. He exists in our yesterday, today and tomorrow simultaneously. As it is proclaimed in Heaven:
“Holy, holy, holy, Lord God Almighty, which was, and is, and is to come.” (Revelation 4:8)
Speaking to those who didn’t believe in the resurrection, Messiah said:
When He introduced Himself to Moses as “I am that I am,” He revealed that He exists eternally and is not bound by our perspective of existence and time. He was, is and will be all at the same time and that is why He is “I Am.” As such, He is not limited by our circumstances and is well-able to deliver us from any situation if we believe that He can and will. He can transform the mistakes of yesterday into a useful lesson that provokes hope for tomorrow.
Blessings and Shalom,
