George Mueller:
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 may be nourished.
…Before this time my practice had been, at least for ten years previously, as a habitual thing, to give myself to prayer, after having dressed in the morning.
Now I saw, that the most important thing I had to do was to give myself to the reading of the Word of God and to meditation on it, that thus my heart might be comforted, encouraged, warned, reproved, instructed; and that thus, whilst meditating, my heart might be brought into experimental communion with the Lord.
…Now what is the food for the inner man? Not prayer, but the Word of God; and here again not the simple reading of the Word of God, so that it only passes through our minds, just as water runs through a pipe, but considering what we read, pondering over it, and applying it to our hearts.
