I heard the phrase “carpe deim” and “seize the day” a lot as a kid, and thinking that it sounded like a reasonable idea. After all, we shouldn't waste our lives wishing and hoping, but never doing. A lot of attention was brought to this phrase by the recent death of Robin Williams, because of his famous speech in the movie Dead Poets Society. Unfortunately, I believe both Williams and his character had the concept of "seize the day" from the wrong angle.
However, I do think there is a connection between “carpe deim” and “carpe aeternatatum.” Just because we should live our lives in light of what matters eternally does not mean that we should lose sight of the opportunities that this life will bring us. I think that there is a difference between living life the way you want and choosing to seize the opportunities life brings your way. The latter is the wiser way to live, especially for the Christian. We should be seeking every opportunity to bring glory to the Lord, and to serve everyone else. “Carpe deim” reminds us that our lives are short, and that's what makes the opportunities we have all the more important. It also reminds us that we have the ability to choose the way our lives go, and that we should be faithful stewards of the free will and talents He gave us.
I want to conclude by sharing a song that my sister sang in church when we were kids called “Seize the Day.” This song has much more biblical approach to the idea of seizing the day. For myself, I personally pray that I am faithful with the gifts He has given me, and that I will be able to make the best of my short time on this earth, so that my eternity will be all the better. That’s what it really means to seize the day.
