Luke 12:32-33 (ESV)

> 
> 32 “Fear not, little flock, for it is your Father's good pleasure to give you the kingdom. 33 **Sell your possessions, and give to the needy. Provide yourselves with moneybags that do not grow old, with a treasure in the heavens that does not fail**, where no thief approaches and no moth destroys. 34 For where your treasure is, there will your heart be also.

Is Jesus commanding his disciples in all ages to sell their possessions and give to the needy?  

Is Luke 12:33 a universal commandment?
