That's all very well - but does it really work? Listen to Sibbes' younger contemporary, Thomas Fuller, as he gives an assessment both of Sibbes' character and - most interestingly - the reason for it.
He was most eminent for that grace which is most worth, yet costs the least to keep it, viz., Christian humility. Of all points of divinity, he most frequently pressed that of Christ's incarnation; and if the angels desired to pry into that mystery, no wonder if this angelical man had a longing to look therein. A learned divine imputed this good doctor's humility to his much meditating on that point of Christ's humiliation when he took our flesh upon him... [This shows us] that men's souls improve most in those graces whereon they have most constant meditation, whereof this worthy doctor was an eminent instance.
This works both positively and negatively. For a contemporary slant on this issue Greg Beale's recent book 'We become what we worship' looks excellent. I haven't read it yet - but I recently heard Beale speaking on the subject, and I came home and promptly ordered the book!
