The Peril of Unbelief

¹² Take care, brothers and sisters, that there not be in any one of you a wicked, unbelieving ^[a]heart [which refuses to trust and rely on the Lord, a heart] that turns away from the living God. ¹³ But continually encourage one another every day, as long as it is called “Today” [and there is an opportunity], so that none of you will be hardened [into settled rebellion] by the deceitfulness of sin [its cleverness, delusive glamour, and sophistication].

¹⁸ And to whom did He swear [an oath] that they would not enter His rest, but to those who disobeyed [those who would not listen to His word]? ¹⁹ So we see that they were not able to enter [into His rest—the promised land] because of unbelief and an unwillingness to trust in God.^(A)
