Our responsibility

Many of us have many things that come under our umbrella of responsibility,  and some of us take on additional responsibilities, often out of a feeling of love for God and for neighbor.  But the one great responsibility that we have, and cas odd as it sounds, it really is the most important, is that of our own holiness.
Saint Seraphim of Sarov, a monk in 18th century Russia, once said, "Acquire the Holy Spirit and a thousand around you will be saved."  In short, this pithy saying is saying, work on your own holiness, i.e., be filled with the Holy Spirit and in doing so, everyone around you will be affected as well. 
As someone once said, "You can't communicate what you do not know."  So despite all the best intentions and love for neighbor, if you do not know and love the love of God, you will never be able to communicate that to your neighbor. And even more so, the closer you are to God, the better you will know him, the more you will understand who God is and the better you will reflect and communicate that love to those around you, usually in more effective ways than you could even devise yourself.
"Acquire the Holy Spirit and a thousand around you will be saved."
