Hebrews 3:12-15

12Take care, brothers and sisters, that none of you has an evil heart of unbelief that falls away from the living God.

13But encourage one another day by day—as long as it is called “Today”—so that none of you may be hardened by the deceitfulness of sin.

14For we have become partners of Messiah, if we hold our original conviction firm until the end.

15As it is said, “Today if you hear His voice, do not harden your hearts as in the rebellion.”
