After a lot of talk about entering into God’s rest (see Hebrews 3:7-4:11), we come to a well-known passage (particularly verse 12).
For the word of God is alive and active. Sharper than any double-edged sword, it penetrates even to dividing soul and spirit, joints and marrow; it judges the thoughts and attitudes of the heart. Nothing in all creation is hidden from God’s sight. Everything is uncovered and laid bare before the eyes of him to whom we must give account.
Hebrews 4:12-13 NIV
https://bible.com/bible/111/heb.4.12-13.NIV
If you’ve been in (or around) church for a while, you might be saying, “Wait a minute! So this is the context where we find this well-known verse?” (i.e., verse 12) All those times that verse 12 was quoted out of context, was the author of Hebrews was actually talking about remaining faithful to our belief of the gospel, and about not falling away from our belief in Jesus?
Now, the message that Hebrews 4:12 carries by itself (i.e., in isolation from its context) is still true and is still helpful. However, it sounds to me like verse 12 isn’t merely a testimony to the value and power of the Bible. Certainly, those things are true, and I’m not judging people who quote verse 12 to drive those points home. However, now we find that verse 12 is explaining the role of God’s word in context. Looking back, we find that the Bible teaches us the gospel: from the Old Testament descriptions of God, symbols of future salvation, and prophecies of Jesus Christ our Savior; to the New Testament gospel and letters and prophecy that show us how God fulfilled His promises to give us rest, despite the obvious gap between our sin and His holiness. In fact, the previous passages of Hebrews had used an example of ancient Israelites to illustrate a key point about belief being key to receiving God’s rest.
In this passage, though, the author of Hebrews says that God knows the truth about our hearts. We may be able to trick other people into believing that we follow Jesus, but God – the decider of who enters His rest – isn’t fooled for even a second. And, this isn’t just some spiritual thing that we’re told, where God knows our innermost selves but we must merely take His word for it. While we can trust God that His word is true, we can also read the Bible and see examples of not only God’s knowledge of peoples’ hearts, but also examples of sins that we’re tempted to commit, along with His love, mercy, and grace for those who sinned (even though God clearly knew that they had done so).
There’s an old song by Steven Curtis Chapman called “The Great Adventure”, which says, “I opened up the Bible / And I read about me” [emphasis added; from Steven Curtis Chapman – The Great Adventure Lyrics | Genius Lyrics].
- We can read the Bible and see how God’s truth applies to us: whether it describes us, teaches us, warns us, or tells us how to know God.
- We can read the Bible and let the Holy Spirit speak to us through God’s Word.
- We can read the Bible and see how Jesus – the Word – saw our sins and loved us so much that He was willing to sacrifice His life for us.
So yes, we are accountable to God for what is in our hearts, and we stand unmasked before God about whether we choose to believe the good news found in His Word. However (and I hope that you have discovered this for yourself), there is incredible power in God’s Word, including the ability to save us, and the power to cut through any facade or wall we might try to put up. This is not a dusty book from the past; it is alive!
Like a sharp sword, let’s allow the Bible to cut through our defense mechanisms – our excuses, our sinful habits, our pretenses. Like a sharp knife, let’s allow it to cut away what keeps our belief in Jesus from growing, allowing God to “help our unbelief”. A commentary [Girdwood & Verkruyse, p.144] says, “When we read other literature, we are in control. When we read the Bible, it is in control.” Control might be difficult for some of us to give up, but you will find no One better to trust with the wheel of your life.
