Devotion to God

A friend just asked about Andrew Fuller, one of the leading lights of the 18th and 19th century Particular Baptists, and a man to be reckoned with in any age. Mention of Fuller always brings to mind one of his most memorable and - for me - compelling counsels. He wrote:
It is to be feared the old puritanical way of devoting ourselves wholly to be the Lord's, resigning up our bodies, souls, gifts, time, property, with all we have and are to serve him, and frequently renewing these covenants before him, is now awfully neglected. This was to make a business of religion, a life's work, and not merely an accidental affair, occurring but now and then, and what must be attended to only when we can spare time from other engagements. Few seem to aim, pray, and strive after eminent love to God and one another. Many appear to be contented if they can but remember the time when they had such love in exercise, and then, tacking to it the notion of perseverance without the thing, they go on and on, satisfied, it seems, if they do but make shift just to get to heaven at last, without much caring how. If we were in a proper spirit, the question with us would not so much be, "What must I do for God?" as, "What can I do for God?" A servant that heartily loves his master counts it a privilege to be employed by him, yea, an honour to be entrusted with any of his concerns.
When each day dawns, will you ask, "What must I do for God?" or "What can I do for God?"
