THE CHIEF LESSONS to be learnt from this parable are as follows:
1. Faith alone does not suffice for salvation, which must be won by good works.
2. At the judgment every Christian will have to give an account of the use he has made of his natural and supernatural gifts. The slothful servant was called wicked and was condemned, simply because he left undone that which he ought to have done.
3. God is our Lord and Master, and we are His servants. He is a most gracious Lord, for He gives His servants more and more grace as they need it, and rewards them with everlasting happiness.
4. Almsgiving. The poor are God's bankers. Alms are a safe investment and bring in the highest interest, for God rewards them with an eternal recompense.
