Reuben’s father Jacob said that he wouldn’t excel because he was unstable as water.
The book of James tells us that double mindedness results in instability.
Nothing creates instability more than following your emotions. In fact, we hear so often, “follow your heart.” The trouble is that my heart is deceitful above all things and desperately wicked.
The surest and quickest path to ruin is following your emotions.
Emotional people quit their jobs on a whim and have no backup plan. Emotional people file for divorce without thinking things through. Emotional people sever friendships over petty squabbles. Emotional people react in violence and spend the night in lock up.
Stability is found by deciding ahead of time what course of action to take and then following it regardless of how you feel at the moment.
It’s not that we do not have emotions. It is that we do not allow them to make our decisions. I never wake up on Sunday morning and ask myself if I am going to church. My emotions do not get to make that decision for me. I never wake up and ask myself if I am going to work that day. My emotions don’t get to make that decision for me.
I make decisions based on right, wrong, principle and faith. Then no matter how I am feeling at a given moment, I am assured I will not do something stupid.
