1. When sin is epidemical, it is sad and fatal to a nation, as in Psalms 14:3 Romans 3:12: so a deluge of sin brought a deluge of judgment, Genesis 6:13,17.
2. This makes the gap great, and leaves none to stand in it. Then the curse comes upon a people, i.e. the punishment of the breach of God's law, Jeremiah 42:18, Jeremiah 44:12. This,
1. Shows the holiness of God's law.
2. It shows the sinfulness and heinousness of sin, the breach of it.
3. It shows the necessity and excellency of Jesus Christ, who was sent of God to bless us, in freeing us from the curse of the law by becoming a curse for us.
