How does sin deceive us according to the Bible?

Hebrews 3:13 warns, 'But exhort one another daily, while it is called Today; lest any of you be hardened through the deceitfulness of sin.' This passage illustrates how sin does not present its true nature at first; instead, it appears attractive and pleasurable. This gradual hardening leads individuals to disregard their spiritual condition, creating a false sense of security. Acknowledging this deceit helps believers maintain vigilance against sin, encouraging continuous fellowship and exhortation within the church. It promotes an understanding that sin is a subtle enemy that can cause eternal harm if left unchecked.
