Hebrews 3:13-15 NIV

[13] But encourage one another daily, as long as it is called “Today,” so that none of you may be hardened by sin’s deceitfulness. [14] We have come to share in Christ, if indeed we hold our original conviction firmly to the very end. [15] As has just been said: “Today, if you hear his voice, do not harden your hearts as you did in the rebellion.”
