Keller/Lovelace connection

The more I read Lovelace and the more I listen to Keller, it is obvious that Keller relies heavily on Lovelace.

If you are familiar with Keller's interpretation of the parable of the prodigal sons, the following citation will sound familiar:

"The Reformers perceived that fallen human nature was touched in every area by the deforming presence of original sin, the compulsive force operating behind individual acts of transgression. They believed that man has freedom of will to do as he pleases but that without the renewing work of the Spirit, he is incurably averse to seeking and serving God. Apart from grace his best actions are built upon the foundation of unbelief, and even his virtues are organized weapons against the rule of God." (Lovelace, Dynamics of Spiritual renewal, 86)
