Adam Smith and Jesus?

"I if I be lifted up will draw all men unto me." - Jesus

Would it be blasphemy to consider this alongside Adam Smith's analysis:

"By pursing his own interest he frequently promotes that of society more effectually than when he really intends to promote it."

There may be a lesson (Principle?) in this for the zealous one who wants to save everybody else, forgetting that his own spiritual growth must lead the way.
