Frist Great and Primary Business of the Day

Here is a great quote from George Mueller's Autobiography.

The point is this: I saw more clearly than ever, that the first great and primary business to which I ought to attend every day was, to have my soul happy in the Lord. The first thing to be concerned about was not, how much I might serve the Lord, how I might glorify the Lord; but how I might get my soul into a happy state, and how my inner man might be nourished. For I might seek to set the truth before the unconverted, I might seek to benefit believers, I might seek to relieve the distressed, I might in other ways seek to behave myself as it becomes a child of God in this world; and yet, not being happy in the Lord, and not being nourished and strengthened in my inner man day by day, all this might not be attended to in a right spirit (Autobiography of George Mueller, compiled by Fred Bergen, [London: J. Nisbet Co., 1906], pp. 152-154].
