Chapter 4 is awesome–if we are willing to heed its advice. What keeps a person from doing so?
Proverbs 4:1-2 Listen, my sons, to a father’s instruction; pay attention and gain understanding.  I give you sound learning, so do not forsake my teaching.
What makes a person unwilling or unable to heed such good advice? There is a lack of understanding concerning the blessings vs. the consequences involved. This lack of understanding comes from a veil that is over their hearts and minds. Only in Christ can it be taken away.
2 Corinthians 3:14 (NIV)
 But their minds were made dull, for to this day the same veil remains when the old covenant is read. It has not been removed, because only in Christ is it taken away.
Paul was talking about The Jews and why they wouldn’t receive the Gospel; the same is true for all mankind.
The promise is in verse 16:
 But whenever anyone turns to the Lord, the veil is taken away.
So, we pray for those who still wear the veil that God would come to them and convict them of sin, for it is in repentance and confession that the veil is lifted and FREEDOM is given:
 Now the Lord is the Spirit, and where the Spirit of the Lord is, there is freedom.
Freedom to do what? To live sin-free! What?! Yes, we are free to live without the spiritual consequences of sin. That price has been paid by the shed blood of Jesus on the cross. From the moment of salvation, we have the desire and the power to live godly lives (Phil. 2:13). We still face the physical, emotional, and psychological ramifications of choosing to sin, but we are free in Christ, never to return to slavery again. The shackles simply won’t lock!
Now, for the promise:
 And we, who with unveiled faces all reflect the Lord’s glory, are being transformed into his likeness with ever-increasing glory, which comes from the Lord, who is the Spirit.
Let’s do everything in our/His power to live for Him today, walking in the Spirit, in sweet fellowship with Christ.
