"For he who is least among you all--he is the greatest." (Luke 9:48)
In this world, there are many foundations you can build your life on. Some might include sports, your job, family, and other things of this world. However, there is a problem with these foundations. They are not stable foundations and can change at an instance notice. A family member could die over night, you injure your knee and your boss could fire you without warning.
However, there is a foundation that will never change and is always there. This foundation is called Christ. He has always existed and always will. If he is the foundation of your life, you will never fall no matter what happens in your life. You are no longer dependent on the world, but on Christ.
