The concept of the uncertainty of life is a recurring theme throughout the Bible, emphasizing the transient and unpredictable nature of human existence. This theme serves as a reminder of the need for reliance on God and the importance of living a life aligned with His will.

Biblical References:

1. James 4:13-14 : "Come now, you who say, 'Today or tomorrow we will go to this or that city, spend a year there, carry on business, and make a profit.' You do not even know what will happen tomorrow! What is your life? You are a mist that appears for a little while and then vanishes." This passage highlights the brevity and unpredictability of life, urging believers to acknowledge their dependence on God's will rather than their own plans.
