The work of salvation in the heart or soul was initiated by Christ, not by the human person - Gordon H. Clark.

The work of salvation in the heart and soul was initiated by Christ, not by the human person. The text does NOT say that because Christ began to work after the sinner had started the good work, He Christ would continue His efforts too.The text says that Christ began the good work.He will also perfect it and complete it, continuing His work throughout the now regenerated sinner's life. Philippians p. 10

Gordon H. Clark.

Gordon Haddon Clark (August 31, 1902 – April 9, 1985) was an American philosopher and Calvinist theologian. He was a leading figure associated with presuppositional apologetics and was chairman of the Philosophy Department at Butler University for 28 years. He was an expert in pre-Socratic and ancient philosophy and was noted for his rigor in defending propositional revelation against all forms of empiricism and rationalism, in arguing that all truth is propositional and thus uses the laws of logic. His theory of knowledge is sometimes called scripturalism.

Clark was a prolific author who wrote more than forty books, including texts on ancient and contemporary philosophy, volumes on Christian doctrines, commentaries on the New Testament and a one-volume history of philosophy
