The Lord expects us to be good and faithful servants, or translated more precisely, "slaves" (Mt 25:14). The fact that the Lord calls us to be His slaves indicates that good stewardship is more than a matter of money. It has become common to speak of stewardship as involving "time, treasure, and talent." This way of approaching stewardship is an improvement and a nice alliteration. However, stewardship is not only giving more to the Lord. It is a matter of slavery — giving all to the Lord. It is a matter of denying ourselves (Lk 9:23) and losing our lives (Lk 9:24).
Stewardship is radical, total giving of the Christian life. Stewardship is giving Him all our money, time, talent, energy, resources, possessions, relationships, opportunities, hopes, plans, desires, etc. The Christian life is not merely a matter of commitment. Work, sports, and education likewise require commitment. The Christian life is a matter of total commitment in imitation of the crucified Christ. Put your stewardship at the foot of the cross.
