When you were a kid, you wanted more than anything for it to speed up. When you were a working adult, you thought no need to hurry or worry because you had plenty of it. When you became a senior citizen, you pondered "Where did it all go?" When you face God, the big question you fear is "How did you spend it?"
Here's the daunting truth: good or bad, you'll have all of eternity to think about your answer. Make the most of today. Be strong (Eph 6:10)
