Being Happy in the Lord

From George Mueller:

It has pleased the Lord to teach me a truth, the benefit of which I have not lost, for more than fourteen years. 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, or 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… 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, by means of the Word of God, while meditating on it, my heart might be brought into experiential communion with the Lord…. How different, when the soul is refreshed and made happy early in the morning, from what it is when without spiritual preparation, the service, the trials, and the temptations of the day come upon one.
