I Corinthians 10:12
Wherefore let him that thinketh he standeth take heed lest he fall.
In his classic book, The Strange Case of Dr. Jekyll and Mr. Hyde, Robert Louis Stevenson tells the story of a man with two natures. Dr. Jekyll realizes he is an “incongruous compound of good and evil.” In this internal fight between good and evil Dr. Jekyll believes that the bad in him is hindering the good, so he develops a potion to separate his two natures. With this potion he can seemingly indulge in his sinful vices without fear of detection as a man named Mr. Hyde. However, one night after taking the potion Dr. Jekyll awakens to the fact that he is far more evil than he realized. He thinks only of self. He is unaware of others, and stops at nothing to gratify himself.
Dr. Jekyll is shaken by what he is capable of and resolves to no longer take the potion. He decides that his focus will be on charity and good works. No more will he allow the evil to come out. Mr. Hyde will be no more.
Months later we find him sitting on a park bench reminiscing about all the good he had done.
I resolved in my future conduct to redeem the past; and I can say with honesty that my resolve was fruitful of some good. You know how earnestly, in the last months of the last year, I labored to relive suffering: you know that much was done for others… But as I smiled, comparing myself with other men, comparing my active good will with the lazy cruelty of their neglect… at the very moment of that vain-glorious thought, a qualm came over me, a horrid nausea and the most dreadful shuddering… I looked down… I was once more Edward Hyde.
This fictional account gives us a stunning picture of how pride works in our life. The very moment we think we have conquered sin and gained victory over temptation is the moment we have already fallen. When you think you are ok, you are not. When you imagine you have beaten temptation, you have already lost. When you think you stand, beware lest you fall.
