Came across this in my devotional reading this morning:
"Indeed, faith without works is the religion of every carnal man. Make an end of one good work, and then begin another, and lay it down, and wonder that Jesus Christ should accept anything at your hands. A true Christian loves to be thus employed, but, above all, he is glad he has the blood of Christ to wash his duties in." -George Whitefield (1714 - 1770)
