A wise man is strong and a man of knowledge increases strength. While the world focuses on physical strength, the greater strength is that which is spiritual.
Perceived strength can be one’s own worst enemy. After all, it leads people to think that they are more powerful and capable than they really are.
Change often results in fear. As such, it must be met with strength. Failure to do so can breed panic that only God's strength can overcome.
During times of battle, believers commonly find themselves to be underdogs. Faith, however, refuses to retreat and trusts God to overcome superior foes.
Thoughts do not have to be wicked in order to be troublesome. Any thought contrary to faith will eventually cause a man to stumble. In Genesis 20:11, Abraham’s thoughts hindered his faith. He perceived that the fear of God was not in Gerar and decided to lie about the identity of his wife in order to insure his personal well-being. Rather than trusting God, he trusted his thoughts. Another example is Naaman. He refused to wash in the Jordan River because he thought that the prophet should have recovered his leprosy by coming out, calling upon the name of the Lord, and striking his hand over the place of leprosy (2 Kings 5:11). When a man trusts in his own thoughts over the words of God, that man shows a complete disregard for truth.
