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. (ESV)
What does it take for people to wander through the wilderness for 40 years seeing God work all kinds of miracles and still in the end rebel against Him? Unbelief. That’s what this passage teaches.
It tells us that no matter how great the miracles that we witness, no matter how great God’s provision is for us, that we have in us a bent toward sin that will take us captive if we let our hearts be hardened by sin. Just as many of the Israelites witnessed God’s continual mercies and still hardened their heats toward him, so do many of us.
Many of us have seen God completely change the lives of people around us, replacing the agony of their lives with the joy of Christ. We have seen Him heal marriages and cure the incurable. We have seen Him change communities and restore families. And yet, we are content to sit on the sidelines and watch Him work in others and never submit our lives to Him and ask Him to do those things in us.
So we wander. Enjoying God’s provision, but grumbling about the way that it differs from what we want or the way we think it should be. And we go after the things that He has warned us to flee from. But because of our unbelief in His sufficiency we replace Him, little bits at a time, with things that feel good and make us feel happy for the moment.
And as we give ourselves to those things our hearts grow harder and harder toward God, and many of us become angry at God because He doesn’t give us the things we want or do for us the things we require.
But in the end, the only thing that we needed was Him.
It is our unbelief, and the unbelief of others around us, that drives us from Him. And we are admonished to “exhort one another every day… that none of you may be hardened by the deceitfulness of sin (v13).”
May we engage each other, and teach each other of the gretness of God so that our unbelief may not harden our hearts toward Him.
I hate struggling with sin. I wish I could just turn my sin off like a light switch, but the truth is, I can’t. And no matter how strongly I believe that I have mastered my sin, it lies behind the well built facade that I live out and begs for attention.
