Take care, brothers, that none of you may have an evil and unfaithful heart, so as to forsake the living God.  Encourage yourselves daily while it is still “today,” so that none of  you may grow hardened by the deceit of sin.  We have become partners of Christ if only we hold the beginning of the reality firm until the end, for it is said:

“Oh, that today you would hear his voice: ‘Harden not your hearts as at the rebellion.’”

Hebrews 3:12-15
