V.1-5 Making promises to friend or stranger is a dangerous thing, because mostly the promises cannot he kept. Only the Lord Jesus could keep His promises (Rom. 4:21).
V.6-11 Laziness surely brings poverty. But there is a deeper lesson. Carelessness and neglect about salvation will bring eternal punishment in hell (Heb. 2:3).
V.12-15 His calamity will come suddenly.
V.16-19 God hates these seven things. Satan is the source of them all. If you take time to think of verses elsewhere in the Bible which tell us this, you will discover how subtle Satan is. (See 1 Tim. 3:6; John 8:44).
V.20-35 God knows that the only thing which can keep us from falling into the traps of Satan, is His Word and obedience to it.
V.22 Three things which the Word does for us. It guides us, protects us, and talks with us.
V.23 The Word of God is a light and it corrects us.
V.24-35 The Word keeps us from immorality. But, as we have been learning in this book, the woman is a picture of subtlety (deceiving) and the man is a picture of violence. In no way is the believer in his Christian pathway more deceived than in religious evil. A little compromise leads to more evil. We see this in verses 28 and 29.
