X is considered a variable in Algebra. It represents a number in a math problem - a number that can change with each problem. X may equal 10 in problem one, and then equal 5 in problem six.
Life is full of variables. Income is a variable. A man can be making a comfortable income one day, and because of circumstances and unfortunate events, he can find himself five years later struggling to make ends meet. The X variable in his life changed on him.
The thing with the X variables in life is that it shouldn't be fully trusted, and we must view it as such. We must actually expect them to change at any given time. An X variable is not a rock on which we can stand on. It is more of a shifting sand under our feet. We cannot treat it as if it will never change on us. If we do, we are setting ourselves up to be highly disappointed and betrayed by it.
Jesus tells us to build our lives on the Rock, which is Himself. He is not a variable. He is constant and unchanging. He won't be one thing for you in problem one, and then change who He is and disappoint you in problem six.
What are you banking on in this life? Are you leaning all your weight on a Variable? If you are, beware my friend. Variables are prone to change. Put your trust and hope in the One who will never change and never disappoint you.
Every good and perfect gift is from above,
coming down from the Father of the heavenly lights,
who does not change like shifting shadows.
James 1:17 NIV
He ALONE is my rock and my salvation,
my fortress where I will never be shaken.
Psalms 62:2 NLT
