Jesus says he will praise those who faithfully and piously use their time and talents while on this earth to minister to others. For the Christian life isn't about finding self and fulfilling self. Life for the Christian is about loosing oneself in service to others. Our focus isn't to be upon ourselves, but upon ministry and service to God and to others. Those who practice good stewardship find purpose and meaning to life by doing what God put us here on this earth to do.
Many people think that life consists of what they have.
But Jesus says that Christian life consists of what we do with what we've been given by his grace. Piety and faithfulness are Christian traits best modeled and imitated. But this isn't true. If you don't do it, chances are nobody will. It's only when you decide to lead by example and choose to serve, that somebody else will too.
