The writer of Hebrews uses the example of the Jews' faithlessness in the wilderness wanderings to deliver a warning. Consider the six lessons taught in Hebrews 3:7-19. 

In Hebrews 3:7-19, the writer addresses 3 groups of Jews:
1. New believers in Christ
2. Jews who are intellectually convinced about Christ as the Messiah, but not committed spiritually 
3. Jews who are not convinced that Christ is the Messiah

The writer of Hebrews draws our attention to 6 things:

1. The Demand for Urgency (Hebrews 3:15)
- Don’t harden your heart by knowingly going your own way rather than God’s way.

2. The Danger of Unbelief (Hebrews 3:12)
- Unbelief never stays self-contained. It can spread. 
- Unbelief in a believer’s life happens when we don’t believe what God says. Unchecked, unbelief winds up in disaster.

3. The Deceitfulness of Sin (Hebrews 3:12)
- Sin tricks you into thinking everything is okay.
- Guard yourself against unbelief.

4. The “Dailyness” of Exhortation (Hebrews 3:13)
- Accountability is critical in the life of a believer. 
- We need to be thankful for others speaking into our lives.
- Do you have humility in approachability?

5. The Discipline of Perseverance (Hebrews 3:14)
- God delights in His children persevering in faith. (James 1:12)
- Do you have unwavering trust in Christ?

6. The Delight of Rest (Hebrews 3:18-19)
- You should be striving for rest in eternity. 
- Rest both now and in eternity is found in Christ alone.
