13 But exhort one another daily, while it is called today; lest any of you be hardened through the deceitfulness of sin. 14 For we are made partakers of Christ, if we hold the beginning of our confidence stedfast unto the end; 15 While it is said, today if ye will hear his voice, harden not your hearts, as in the provocation (Hebrews 3:13-15).
The writer of Hebrews is warning people not to get stuck in sinful ways. What happens over time is that sin becomes a way of life and crowds out the ability to live for Christ. We are to guard ourselves against persistent sin since eventually we will develop a hardened heart as a result of this sinning. Once the heart is hardened it can be impossible to undo. The road to destruction can be very subtle at first and may start with minor compromises but the road is destructive and without turning away will lead to eternal death.
