I was just thinking about the scripture "And he who receiveth all things with thankfulness shall be made glorious; and the things of this earth shall be added unto him, even an hundred fold, yea, more" (D&C 28:19).
First of all, that's both a difficult commandment to keep and a blessing that certainly attracts the eye of anyone who either (a) has trouble supporting themselves, (b) wants money for its own sake, or (c) wants to use money, directly or to free up personal time for service, for the benefit of others.
It just occurred to me that this promise could apply to blessings of talents, spiritual gifts, or Christlike virtues. If we, by the grace of Christ, develop a new ability, we can respond in several ways. If we respond with gratitude to these blessings, then we will continue to receive until we have received a hundred times what we started with and beyond. If we respond with pride, thinking that our virtues lend us some sort of superiority or independence from God, then we will fall.
Gratitude leads to humility. We are reminded that although we may have gained something through effort, it was through a combination of effort and grace. Merit and entitlement have no place in our growth from grace to grace (D&C 93).
