If the story of Samson is any indication, men can have all the God-given strength in the world and still be thwarted by our own temptations. No matter how strong we are physically or mentally it means nothing if we are not spiritually strong.
The only protection against sin is our reliance upon the Word and Power of God. If we turn to God in times of weakness, asking for guidance and protection, He will give us the wisdom and fortitude to overcome anything Satan throws at us.
That's why I love the story of Samson. Despite everything he's lost, despite everything he's been through, even in his last dying moment he finds strength in his weakness and relies on the Power of God to help him vanquish his enemies. Like Samson, we cannot fight the enemy alone. For us to heal, grow, and thrive we need the Power of God every step of the way.
