Generational Curses 02
The source of blessings and curses
James 1:17 NIV
Every good and perfect gift is from above, coming down from the Father of the heavenly lights, who does not change like shifting shadows.
Genesis 12:1-3 NIV
The LORD had said to Abram, "Go from your country, your people and your father's household to the land I will show you.  "I will make you into a great nation, and I will bless you; I will make your name great, and you will be a blessing.  I will bless those who bless you, and whoever curses you I will curse; and all peoples on earth will be blessed through you."
Deuteronomy 28:3-14 lists the blessings that will overtake us as we listen and obey God's voice. Prince summarizes these blessings as exaltation, health, reproductiveness, prosperity, victory, and God's favor. As you read through the blessings there is little else a person could want in their life. There is only one requirement obedience.
Genesis 27:27-29 records Issac's blessing to Jacob. If you read the account of Issac blessing Jacob in Genesis 27:1-29 you will realize that Jacob stole the blessing by deception. And when Issac realized who he actually blessed, he also knew that the blessing could not be undone. Because he had pronounced the blessing on behalf of God. But, I believe, it was God's intention to have Jacob blessed. Romans 9:13 NIV quotes Malachi 1:2-3 saying "Just as it is written: "Jacob I loved, but Esau I hated.""
Genesis 27:27-29 NIV
So he went to him and kissed him. When Isaac caught the smell of his clothes, he blessed him and said, "Ah, the smell of my son is like the smell of a field that the LORD has blessed.  May God give you heaven's dew and earth's richness— an abundance of grain and new wine.  May nations serve you and peoples bow down to you. Be lord over your brothers, and may the sons of your mother bow down to you. May those who curse you be cursed and those who bless you be blessed."
The opposite of blessing is curse. Blessings and curses are words, generally spoken, with some spiritual authority that sets in motion consequences that may last for generations.
Exodus 20:5-6 NIV
You shall not bow down to them or worship them; for I, the LORD your God, am a jealous God, punishing the children for the sin of the parents to the third and fourth generation of those who hate me,  but showing love to a thousand generations of those who love me and keep my commandments.
Where does a curse come from? A curse may be pronounced directly by God, pronounced by man on behalf of God, pronounced by someone with relational authority over a person, may be self imposed, may be the result of a larger group you belong to, or may be a direct attack of the enemy. It is important to note Proverbs 20:2.
Proverbs 26:2 NIV
 Like a fluttering sparrow or a darting swallow, an undeserved curse does not come to rest.
