Comparing the widow's acceptable offering to Cain's unacceptable sacrifice reveals that we must give offerings to become acceptable and satisfying to God. Our offering must be a total sacrifice — total commitment, wholehearted, given in zeal and energy, with a view of becoming totally consumed, as depicted in God's numerous examples of completely consuming offerings by fire. As living sacrifices, we must give our lives totally consumed in zeal to the service of God. Like the widow, we must give with the purpose of being totally consumed.
