2 Peter 3:8 – But, beloved, be not ignorant of this one thing, that one day is with the Lord as a thousand years, and a thousand years as one day.
Have your opinions changed since you were younger? Do you like different foods? Do you know more about your career? Have you gotten married? What about children? There are so many things that affect our understanding of the world around us, and our perspective changes each time we learn something new. Not so with God.
By definition, God is eternal. He exists beyond the dictates of Creation. He has power over it, but it has no power over Him. At least in part, God is all-knowing, because His eternal nature allows Him to see all creation at once. He not only sees everything going on everywhere now, He sees everything going on in the past and the future. He is the great I AM.
As in so many other ways, Jesus Christ demonstrated His divine nature in His perspective on events. He knew things before they happened, and He had perfect understanding about the past. His long-suffering and patience also spoke to a grand knowledge beyond normal human comprehension. Even in simple things Jesus revealed God’s understanding such as when He said, “…your Father knoweth what things ye have need of, before ye ask him (Matthew 6:8).
With these things in mind, it makes sense that Peter would emphasized God’s timeless nature. We may be limited to seeing our lives minute by minute and day by day, but God knew us yesterday, and He knows our tomorrow. He is the Alpha and Omega, the beginning and the end.
