In our lives, we know 24 hours is one day, 7 days is one week, and 12 months is one year.
To God, one day is a thousand years.
Make each one of your thousand years, count for something.
II Peter 3:8 (KJV) – 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.
