I trust a different intrepretation of this scripture. It says in (Luke 17:10 So likewise ye, when ye shall have done all those things which are commanded you, say, We are unprofitable servants: we have done that which was our duty to do.
The unprofitable servant is spoken of in (Matthew 25:30 And cast ye the unprofitable servant into outer darkness: there shall be weeping and gnashing of teeth. )
Because we do our duty and trust in God giving the abundance of fruit. We continue to share all that we have with others, or we are unprofitable servants.
The entire message of (LUKE 17:7-10) was in response to the apostles request of more faith. To answer, faith, and duty we understand how we receive abundantly when we do our duty. It is not just given with no intention of it's using or growing. The fruit is not given to any that stand to profit nothing in it.
As servants of our Lord we do trust in HIS abundant mercy and grace. And we avoid foolishness that is unprofitable and vain.
Hebrew 13:21 Make you perfect in every good work to do his will, working in you that which is wellpleasing in his sight, through Jesus Christ; to whom be glory for ever and ever. Amen.
