What is the one thing necessary?

In preparing to retire, I find that my life is still cluttered with "things." The One Thing Necessary, however, is hearing the word of God and living by it. To do this, I must stay in the now, not in the past or the future, but here, now, which is the one time and place I am actually connected with God. So, I let go of reputation, workaday life, status, possessions, money, everything except right here and right now. And then this next moment, I do so again. And again. And now. and now. Maranatha!
