What is True Christianity?

"...it is a faith that is lively and full of vigour, so that it spares no labour, when assistance is to be given to one's neighbours, but, on the contrary, all the pious employ themselves diligently in offices of love, and lay out their efforts in them, so that, intent upon the hope of the manifestation of Christ, they despise everything else, and, armed with patience, they rise superior to the wearisomeness of length of time, as well as to all the temptations of the world."

-- John Calvin, in his commentary on 1 Thess. 1:3
