7 Therefore, as the Holy Spirit says,
“Today, if you hear his voice,
8 do not harden your hearts as in the rebellion,
on the day of testing in the wilderness,
9 where your fathers put me to the test
and saw my works for forty years.
10 Therefore I was provoked with that generation,
and said, ‘They always go astray in their heart;
they have not known my ways.’
11 As I swore in my wrath,
‘They shall not enter my rest.’”
12 Take care, brothers, lest there be in any of you an evil, unbelieving heart, leading you to fall away from the living God. 13 But exhort one another every day, as long as it is called “today,” that none of you may be hardened by the deceitfulness of sin. 14 For we have come to share in Christ, if indeed we hold our original confidence firm to the end. 15 As it is said,
“Today, if you hear his voice,
do not harden your hearts as in the rebellion.”
DO NOT HARDEN YOUR HEARTS.
Certainly, no believer plans to become cold and hard hearted. Does anyone plan to miss praying, reading the bible, worship, or fall away? A little neglect can have disastrous effect. But, for many Christians, it’s a sad reality that hits them in the face. And even more pathetic, that they’re oblivious that they’re one.
The hardening of one’s heart isn’t overnight. It is a slow process. A guy who walk barefooted for the first time may grimace for pain at every time he steps upon a rugged pavement. But, overtime, his sole will grow callous so that he won’t feel the pain anymore. And, such were the Jews who may had hardened as they accustomed and not bothered anymore by the scorching heat of the sun at the wilderness.
In verse 7, the writer has warned us quoting Psalm 95. It’s a result of rebelling against the promptings of the Spirit. “He will convict the world concerning sin and righteousness and judgment: concerning sin, because they do not believe in me; concerning righteousness, because I go to the Father, and you will see me no longer; concerning judgment, because the ruler of this world is judged.” [John 16:8-11] The Jews had heard God’s voice but they vehemently refused to listen.
Moreover, they had witnessed the work of God for 40 years. The manna, Pillar of clouds and fire did not fail day by day. The favor of God to them was overwhelming. Yet, they refused to honor God and had provoked Him to anger. As in a perfect ultrasound scan, God’s diagnosis was thorough - ‘They always go astray in their heart; they have not known my ways.’ The heart of the matter is the matter of the heart.
How could we prevent from becoming hardened?
Know your heart. Jeremiah said,
“ The heart is deceitful above all things,
who can understand it?” [Jer 17:9]
Thus, we must take care of our hearts. “Keep your heart with all vigilance, for from it flow the springs of life.” [Prov 4:23]
Thus, we need also the “exhorting one another” among ourselves, i.e. an accountability group. Speaking the truth with one another in love [Eph 4:25]. Sin is deceitful, isn’t it? The momentary pleasure of sin gives could blind us of its catastrophic consequence later. Nobody is too smart and strong that can handle the effects of sin. “Whoever conceals his transgressions will not prosper, but he who confesses and forsakes them will obtain mercy.” [Prov 28:13]
Brethren, please do not harden your hearts today. Open your heart to the Spirit's promptings, by praying, “
“Search me, O God, and know my heart!
Try me and know my thoughts!
And see if there be any grievous way in me,
and lead me in the way everlasting!” [Psa 139:24,25]
