“And Jacob worked seven years for Rachel, but they seemed to him like a few days because of his love for her.” (Genesis 29:20)
Actually, when we wait impatiently for something, a day can feel like a year. How could having to work for seven years for Rachel have seemed like just a few days to Jacob?
The explanation is that because of the great love he had for Rachel, having to serve he father for only seven years was a small price. Waiting seven years seemed like a few days.
