My Father-in-law Ken is currently reading a book that's way older than me. I don't even know what it is, but he shared a fantastic quote with me this morning:
"Samson lived without friends and died with out mourners. His strength was his destruction."
It is often your best attributes that lead to your downfall. Your intelligence, your physical beauty, or your ability to accomplish is often the thing that leads to your isolation, your arrogance, or your self-righteousness. This dovetails perfectly with a verse of Scripture I have been thinking on often.
Isaiah 7:9 "If you don't stand firm in your faith, you will not stand at all."
In what area of your life are you standing firm in your own strength instead of the unique strength of Christ? If it is yielded to the lordship of Christ it can be a great blessing to the world. If it is twisted for your own self-justification it can be the thing which damages your soul the most.
Ephesians 6:10 "Finally, be strong in the Lord and in his mighty power."
