Redefining sin

Tim Keller’s redefinition of sin, in his book Every Good Endeavour (2012), into two categories, namely, thin sin and thick sin is profounldy unbiblical. He is promoting a false version of Christianity that adopts a thick view of sin; a view that encourages Christians to engage in worldly conduct and downplays the importance of holy living. Yet Scripture warns that friendship with the world is enmity with God.
