For me, the action that corresponds to me loving God is total surrender - an opening to allow God-as-Love to flow through me and into the world. As Krishna says, to be "the mere instrument"... 

I am struck by the fact that as a Greek speaker I didn't know that faith - pistis, is receiving and love - agapi, is giving - which goes to show that we get so stuck in a particular usage of a word in our world / culture and cannot see beyond it.  Thank you so much for this guiding principle which was strongly brought to me by these two words here
