A balance

Amidst the constant thought of loving neighbor,  one way that manifests itself is in helping the poor. One question that keeps coming to my mind is that of balance.  Is there a balance between the money we keep for ourselves and the money we give to the poor? Or how about our time?  How much time do we keep for ourselves versus giving to others?
It is very easy to look at others, especially the wealthy and assume that they are not doing enough.  But who's to say?
An early church father commented that if we have two coats, one of them is actually stolen from the poor! It's a big question to think about and one that will probably make us uncomfortable.
