Richard Sibbes, on work, etc.

But take this caution withal, that we more highly esteem our Christian calling than our ordinary vocations and duties; and to that end we ought to redeem some time from our ordinary callings to meditate, and to examine ourselves, and to pray. And this is to be done daily, for Christ saith, 'Labor not for the meat that perisheth,' in comparison of that meat which lasteth forever. Especially on that day which God hath chosen to his own use, I mean the 'Lord's day.' Mingle not thine own callings with holy duties on such days, unless it be in case of mercy, and that also of great necessity. God made this day for his own glory, and for our good, knowing how earthly-minded else we would be, unless some time were allotted wholly to vindicate our minds from these earthly things.

I love seeing quiet times extolled. But I wonder about the passion they took to their Sabbaths. Any thoughts?
