What does Psalm 90:2 mean?
Here, in what is likely the oldest of all the psalms, Moses answers a question which comes up even today: When did God begin? The answer is that He did not "begin;" He has always existed, and He always will exist. He is eternal, without beginning or end. He lived before He formed the mountains and brought the earth and the universe into existence. This is not merely something Scripture claims. It is also a logical necessity—there must be one un-created and un-caused "something" to originate everything else. Otherwise, there could never be anything, at all.The Son of God is also eternal. He described Himself to the apostle John on the island of Patmos as "'the Alpha and the Omega…'who is and who was and who is to come, the Almighty'" (Revelation 1:8). John 1:2–3 affirms that the eternal Son of God "was in the beginning with God," and "all things were made through him, and without him was not any thing made that was made." The Holy Spirit, the third member of the Trinity, is also eternal. Hebrews 9:14 tells us Jesus offered Himself as the flawless sacrifice "through the eternal Spirit." Father, Son, and Holy Spirit are the eternal members of the Trinity, and each played a role in creation. The Father spoke everything into existence through His Son, and the Holy Spirit hovered over the face of the waters (Genesis 1:1).
