Hebrews 3:12-14 NIV

[12] See to it, brothers and sisters, that none of you has a sinful, unbelieving heart that turns away from the living God. [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.
