Hebrews 3:12-15
3:12 See to it, brothers and sisters, that none of you has an evil, unbelieving heart that forsakes the living God.
3:13 But exhort one another each day, as long as it is called “Today,” that none of you may become hardened by sin’s deception.
3:14 For we have become partners with Christ, if in fact we hold our initial confidence firm until the end.
3:15 As it says, “Oh, that today you would listen as he speaks! Do not harden your hearts as in the rebellion.”
