Origin and Nature of Self-Deception in Human Heart
The concept of self-deception in the human heart is deeply rooted in biblical texts, particularly in the Old Testament prophet Jeremiah. Jeremiah 17:9 states, "The heart is deceitful above all things and beyond cure. Who can understand it?" [1]. This verse highlights the inherent corruption and inscrutability of the human heart, suggesting that its deceitfulness is profound and pervasive [4].
This biblical understanding of the heart's nature is foundational to Christian theology regarding human sinfulness. Charles Hodge, in his Systematic Theology, explains that the Scriptures assert the human heart is "desperately wicked," which aligns with the Church's doctrine of human depravity [5, 6]. This depravity is not merely a result of individual actions but is inherent in human nature itself, determining conduct to be either good or evil [6]. Just as corrupt fruit indicates a corrupt tree, universal sinfulness points to an evil human nature [6].
The deceitfulness of the heart leads to various forms of evil. Jesus, in Matthew 15:19, states, "For out of the heart come evil thoughts, murders, adulteries, sexual sins, thefts, false testimony, and blasphemies" [2]. This passage underscores that sinful actions originate from within the heart. John Gill, commenting on Jeremiah 17:9, notes that the heart deceives individuals regarding sin, presenting it as pleasurable while failing to deliver genuine satisfaction [7]. This self-deception is a fruit of sinful human nature and can lead to folly [3].
The recognition of this inherent deceitfulness and wickedness in the human heart is crucial because it implies a need for external intervention. If individuals were capable of curing themselves, seeking help from outside sources would be illogical [8]. The biblical perspective suggests that only the Lord truly comprehends the extent of this internal corruption [4].
