The world, through its perspective, ultimately blames God for the self-centered and self-serving nature of humanity, suggesting that He created a deceitful and desperately wicked heart, as described in Jeremiah 17:9. This heart is so corrupt that it is beyond human comprehension, deemed incurably sick by God Himself. Yet, Scripture clarifies that God did not create this evil heart; He gave Adam and Eve a spirit described as very good in Genesis 1:31. Mankind became corrupted through contact with satan, who introduced sin through Adam and Eve, and this corruption has been passed on to all born from them as they submitted to his influence. Sin is far more than visible actions; it is a vast, contagious, and forceful moral disease affecting all of humanity. As Jesus explains in Matthew 15:19, out of the heart proceed evil thoughts, murders, adulteries, fornications, thefts, false witness, and blasphemies, which defile a person. The heart is the source of this defilement, representing the innermost being where sin resides as a motivating influence akin to spirit, driving actions that appear outwardly. This sinful nature is a product of satan's mind, inculcated through contact with him, his demons, and the worldly systems he created, reflecting pride, envy, lust, bitterness, anger, and hatred. Even the apostle Paul, in Romans 7:14-23, admits to the presence of sin within him, describing it as a carnal influence, an evil presence, and a law warring against the mind, bringing captivity to sin. This indicates that sin is not merely the act but the internal force motivating wrongful behavior, a constant influence even in a converted person. Sin, therefore, consists of thinking, saying, doing, or imagining anything not in conformity with God's mind and will, an inward and outward departure from His revealed character. Scripture also highlights sins of omission, as seen in Matthew 25:40-46, where failing to act—such as not feeding the hungry or clothing the naked—is counted as sin, leading to severe consequences. Additionally, unintentional sins, as addressed in Numbers 15:25-29, still require atonement despite the lack of intent, showing that ignorance does not excuse guilt, though the punishment may be lighter, as noted in Luke 12:47-48. The ever-present influence of sin demands vigilance and a close relationship with God to mitigate its effects and pursue holiness, without which no one will see the Lord, as urged in Hebrews 12:14.
