A person with firm convictions can become pigheaded. A person who is inclined to be temperate and judicious can sometimes turn into someone with weak convictions and banked fires of resolution . . . Loyalty can lead to fanaticism. Caution can become timidity. Freedom can become license.
Confidence can become arrogance.
Humility can become servility. All these are ways in which strength can become weakness. But when the Lord is your Fortress, then His strength can become your strength. When we do face huge mountains. When enormous problems stare us in the face.
