The Gospel from Matthew 25: 14-30 speaks to Stewardship directly. "Out of fear, I buried it".
The three parables in the twenty-fifth chapter of Matthew are about the end times, the end of the world, the end (intent, purpose, and upshot) of our lives. Whatever is given to us—money, talent, opportunity—is meant to bear fruit for the kingdom, for the glory of God and the salvation of souls.
In its most fundamental sense, the image of the talent represents the bounty of life itself, as well as the preeminent gift of faith. If we are among those fortunate enough to reach the maturity required for personal responsibility and to have the opportunity to use the talents of life and faith, it is incumbent upon us to invest our gifts, not hide them out of fear or laziness.
The parable is not about the stock market or entrepreneurship, commendable as those activities might be. It is about what we do with our gifts, financial or otherwise.
The goods of the world and the wealth derived from our labor must be used for God's glory and human assistance. What is more, if a Christian would defend the benefits of capitalism, it ought to be based on the argument that capitalism is most effective in the service of God and ministry to the poor, homeless, and hungry.
