But exhort one another daily, while it is still called “today,” lest any of you be hardened through the deceitfulness of sin. (21st Century King James Version) - Hebrews 3:13

But search your hearts daily, until the day which is called The day, to the end that no man among you be hardened through the deceitfulness of sin. (Peshitta) - Hebrews 3:13

In my preferred Bible translation, the Peshitta, this verse reads a bit differently - not that one is better than the other, just that it reads differently and I really enjoy the differences and both of them indicate to me two different acts that I should be doing.

There are three key things in this verse:

1. Exhort one another daily (search your hearts daily)
   
2. you can be hardened
   
3. the deceitfulness of sin
   

Exhort one another:

How do we exhort each other? Hebrews 11:24 tells us to "stir up one another to love and good works, not neglecting to meet together, as is the habit of some, but encouraging one another."


Search your hearts daily:

Psalm 4:4 encourages us to "commune with your own heart and meditate upon your bed"


you can be hardened

Proverbs 28:13-14 has this to say about your heart being hardened, "Whoever conceals his transgressions will not prosper, but he who confesses and forsakes them will obtain mercy. Blessed is the one who fears the Lord always, but whoever hardens his heart will fall into calamity. "


the deceitfulness of sin

Ephesians 5:22 encourages us to "to put off your old self, which belongs to your former manner of life and is corrupt through deceitful desires"


Three or four valuable lessons here for the Christian, yet all of them uniquely intertwined. We who are believers of God are to seek out other believers with whom we can encourage and be encouraged by, we are to search our hearts and try to make things right with ourselves every day - and failure to do so could eventually lead to no longer fearing the Lord, will eventually become knotted up inside over unresolved turmoils, and from there our lives could become like our former life. I am reminded of Ezekiel 36:26, "remove the heart of stone from your flesh and give you a heart of flesh".

If you are finding that your heart is hardening, examine these verses and try to put them into reverse: Except that your heart has become hardened, search your heart on how to make things right, find others with whom you can once again be encouraged by.
