The Uncertainty of Life


We never actually know what each day will hold because life is full of uncertainties.  James 4:14 says, “You do not know what your life will be like tomorrow. You are just a vapor that appears for a little while and then vanishes away.” 

I was born without the left side of my heart (hypo-plastic left heart syndrome), which is needed to provide oxygen-rich blood to the body. Without successful surgery the diagnosis is fatal.

To survive, we require a specialized pump that can deliver life-giving blood to all our body parts, day and night, year after year, without fail. To get the job done within the body of a living organism, the heart must overcome some incredible engineering challenges. Our lives hang on a thread. A constant flow of rich blood must reach cells throughout the body, delivering oxygen and essential nutrients to our extremities, while removing waste products like carbon dioxide. Stop the flow for just a few minutes, and life will cease. Heather M. Brinson

That is pretty humbling to read. Just think about it for a moment...every single heartbeat is in the hands of our Creator. God has determined our days here on earth and we are here for His purpose and His glory (Psalm 139:16; Job 14:5).

My heart condition is a physical daily reminder of this truth. Even though my heart is fixed up to function, it is still not whole and does not function the same way a normal heart does. My condition comes with many daily limitations and daily reminders that my heart is still indeed broken. I am constantly reminded of the uncertainty of my heart between medications, arrhythmia (fast heart beats), irregular beats, shortness of breath, chest pain, and the ever-looming possibility of surgeries in the future.

However, in reality though my physical heart is broken, my next heartbeat is no more uncertain than that of a person with a whole working heart because ultimately every single heartbeat, of every person, is in God’s hand. It is God who chooses whether or not to keep this broken heart beating, just as He keeps yours beating. I just have a daily reminder of this.

So even in the midst of the pain and fear of the uncertainty of life, comfort and rest is found in Jesus. For the Lord is Sovereign, Loving and All Wise and we can indeed trust Him and His ways, even when we don’t understand. Isaiah 55:8 says, “For My thoughts are not your thoughts, nor are your ways My ways,” declares the Lord. “For as the heavens are higher than the earth, so are My ways higher than your ways and My thoughts than your thoughts.” The Lord’s ways are higher than ours and His Plan is perfect. 

One day every heart will fail. The question is, will you be ready? Remember the words of James, “You do not know what your life will be like tomorrow. You are just a vapor that appears for a little while and then vanishes away.”  This life here on earth may be full of uncertainties, but there is one thing we can know for certain; we will all one day die (unless you are living during the rapture of the Church). Psalm 144:4 says, Man is like a mere breath; His days are like a passing shadow.” So what does this mean? How then should we live our lives?


We should live our lives with our eyes and hearts fixed on Jesus.

There have been moments where I have been unsure if my heart will give out or keep on beating and in those times the last things on my mind were the fleeting things of this world. All I could think about was how much time I had wasted on meaningless things and how much greater eternal matters are. Theologian, J.C. Ryle, puts it this way, “There are many things which swallow up men’s thoughts while they live, which they will think little of when they are dying.” How true this is! When you are aware of the uncertainty of life, you are more aware of the vanity of life that we spend living under the sun (Ecclesiastes 2:11).

This life is constantly reminding us of the brokenness all around us and inside of us. This world and our spiritual hearts are tainted by sin. Though we can’t control the brokenness around us, we can control our own sinful thoughts, attitudes, words and desires. Our spiritual hearts are corrupted by sin and we are all in desperate need of a new one. Jeremiah 17:9 says, “The heart is more deceitful than all else and is desperately sick; who can understand it?” We are all dead in our trespasses and sins (Ephesians 2:1), born separated from God and in need of His saving grace. God so graciously sent His Son, Jesus Christ to take our place and to pay our debt for sin (1 John 4:10). In Jesus Christ, our sin is covered and we are made new creatures and given a new heart (2 Corinthians 5:17). It is only through Jesus Christ that our spiritual heart condition is healed, that we are restored to a right relationship with God, and that we can forever live in eternity with Him and be set free from the bondage of sin. 


“My flesh and my heart may fail, but God is the strength of my heart and my portion forever.” Psalm 73:26

This life is fleeting and we never know when our time will end or what our day will hold. No day is guaranteed to us. So, remember the uncertainty of life, fix your eyes on Jesus and His glory and share His name with others.

Only one life, twill soon be past, Only what’s done for Christ will last.” – C.T. Studd
