I recently came across this Dr Guthrie quote in his book 'The Angels Song' which is available as a Kindle book. It is vintage Guthrie and as always reveals his great respect for the Christian involved in the nitty gritty of everyday work.
"But people are too apt to suppose that religion lies mainly, if not exclusively, in prayers, reading the Bible, listening to sermons, and attending on sacraments; in time spent, or work done, or offerings made, or sacrifices endured, for what are called, in common language, religious objects. These are the means, not the end. He who rises from his knees to his daily task, and, with an eye not so much to please men as God, does it well, carries divine worship to the workshop, and throws a sacred halo around the ordinary secularities of life. That, indeed, may be the highest expression of religion; just as it is the highest expression of devoted loyalty to leave the precincts of the court and the presence of the sovereign, to endure the hardships of a campaign, and stand in soiled and tattered regimentals by the king's colours amid the deadly hail of battle. He who goes to common duties in a devout and Christian spirit proves his loyalty to God; and, as this case proves, is of all men the most likely to be favoured with tokens of the Divine presence--communications of grace which will sustain his patience under a life of toil, and fit him for the rest that remaineth for the people of God."
