From Puritan Thomas Goodwin [Works, 5:292 (print|electronic)]:
…faith is to look at once with one eye to heaven, to Christ there as risen, ascended, interceding, so to look down with another eye to that Christ as once crucified and hanging on the cross, as made sin and a curse.

While Reformation Heritage Books is a great publisher, I prefer the hardback edition of Goodwin’s Works from this publisher for the same price: http://www.sgpbooks.com/cubecart/Books/Sets-Library-Works/Works-of-Thomas-Goodwin-12-Volume-Set-hard-cover-set/prod_58.html. They also have free shipping right now.
