12 Take care, brothers and sisters, that none of you may have an evil, unbelieving heart that turns away from the living God. 13 But exhort one another every day, as long as it is called "today," so that none of you may be hardened by the deceitfulness of sin.14 For we have become partners of Christ, if only we hold our first confidence firm to the end. (Heb 3:12-14 NRS)
