Who Knows for sure?
In Proverbs 27:1 it says boast not thyself of tomorrow; for thou knowest not what a day may bring. Man has no way of knowing for sure what will happen from one day until the next. We have no way of knowing for sure what tomorrow will bring. Everything may be going fine for you right now but a trip to the grocery store could change your life forever. God has not given any of us to command one moment of the future.
We do know that our lives can take a turn at any given moments.
We do know that life is compared to a vapor. James 4:14
Vapor is smoke, always fleeting, always uncertain, it passes swiftly and no man knows for certain when his day will come.
It is ok to plan for the future, but as we all know many times we make our plans and then we have to modify them to match His plan.
We have to understand that tomorrow is uncertain we see an account of a man in Luke 12:19,20 Who was so sure he had tomorrow he had planned on building bigger barns to store his good.
Selfishness and greed will get you every time. It may not kill you physically, but it will spiritually.
