In his letter to the Romans, as Paul begins unfolding his argument for our need of salvation (both Jew and Gentile), he indicates that our sin and guilt is associated with the fact that God had made truth about Himself known to us but we suppressed this truth in order to do what we wanted; we “suppress the truth in unrighteousness” (Ro.1:18). He does not indicate that we lacked ability to understand or respond to the truth correctly. He refers to the active, accountable act of suppressing the truth. He does not say that we are without ability, he states, to the contrary, that we are “without excuse” (Ro.1:20).
Such points have very practical implications. These are fundamental truths that quickly challenge certain theories about sin that have become quite popular in some Christian circles. It is truth that also affects the way we interact with people in the evangelistic process. One of the obstacles to genuine repentance is the idea that there is a legitimate reason (excuse) for the sin that is being committed. Regardless of what the excuse consists of, the job of the wise minister is to eliminate that which serves to shield them from necessary conviction which potentially leads to repentance, conversion and deliverance. Too often our doctrine of sin reinforces the excuses set forth and becomes a barrier to conversion. Dealing with the excuses and “hiding places” of sinners requires wisdom. This is why Proverb 11:30 states, “…he who is wise wins souls” and Jesus told His disciples, “Behold, I send you out as sheep in the midst of wolves; so be shrewd as serpents and innocent as doves” (Mt.10:16). Charles Finney writes, “…I felt it my duty to expose all the hiding-places of sinners, and to hunt them out from under those peculiar views of orthodoxy, in which I found them entrenched.”
 The secular world blames genetics, environment, upbringing, parents, bullies, animal instinct, etc. for human behavior while the Christian world comes up with doctrines of inability, born sinful, sinful nature, etc.
