Doing something, 2

It is probably safe to say that the main goal of the Christian faith is that is sanctification.  We must strive, endeavour and work to the point of extreme, at purifying our souls.  The corrupting influence of sin has become so common, typical and even comfortable, that we have lost all appropriate perspective of it.  Sin is horrible, ugly, and ultimately damning, that we must continually recognize its true nature.
All of this is an absolutely necessary part of our lives.  We must eradicate sin from our lives.  In addition to this, what are we to do?  I think the easiest answer is that of love.  We must love OUR neighbor.  This means that how that love manifests itself will look different for each one.  Regardless of one's situation, I believe that the way that love lives itself out is specifically, never in general.  Love is always specific.  The neighbor lady, the stock boy at the grocery store, the mailman, our co-workers, etc.  This is one reason that the church simply does not do door to door, it is too impersonal to be successful.  The same goes for mass evangelism. To love is to love specifically.
To put a somewhat finer point on this, we should make use of our strengths as well.  In whatever way we have strengths or abilities, these we can use for the good of others.  It is far too easy to fall into selfishness, even to be point of no longer seeing it.  If we can step back and objectively analyze ourselves, do so.  If we cannot, a spiritual father can help us see ourselves, typically in ways we cannot do ourselves.
So what to do? There is no list, there is no specific ideal. Everyone is different.  But we must do something.  Begin by speaking with your priest.
