Isaac trembled violently and said, 'Who was it, then, that hunted game and brought it to me? I ate it just before you came and I blessed him ? and indeed he will be blest!' (Genesis 27:33).
Blessings are strange things: they are only words coming from the mouth of God or through some other person and yet thy can determine the course of one's life.
In the Book of Numbers, Balak wanted Balaam to curse the Israelites, God's chosen people, because they had become too prosperous and he hated them. He promised Balaam that he would reward him richly and give him whatever his heart desired if he would only curse the Israelites. Balaam, a prophet of God, with no heart for God, was taken in by the King's offer and would have cursed the Israelites, if he could, but God stopped him. Each time Balak tried to manipulate Balaam into cursing the Israelites, only words of blessings from God came out of Balaam's mouth. Finally Balaam told the King:
I have received a command to bless; he [God] has blessed, and I cannot change it (Numbers 23:20 NIV).
But it is not just the blessings of God, which carry this eternal weight. Man's blessings are very similar to the blessings of God.
Both Jacob and Esau understood the value of receiving the blessing (good words) of their aged father before he died. The blessing rightfully belonged to Esau, the oldest son but Jacob sought to rob his brother of his blessing (words). So he dressed in his brother's clothes and did everything that would convince his blind father that he was his brother. The old man was deceived and pronounced the blessing (good words) over Jacob.
When Esau returns for the blessing of the oldest son, he was devastated when his father told him he had already spoken the blessing over his brother. Esau cries out to his father to bless him anyway. But Isaac tells Esau that he has already blessed Jacob, 'and he shall be blessed.' That means he could not retract the blessing. He could not take it back. It was the blessing of God given to the father to speak over his eldest child. Jacob turned out to be head of his brother.
What happens to children, teenagers, even adults today when no one blesses them; when neither father, mother or grandparents speak the promises of God into their life? They are left vulnerable for any evil be spoken over them and affect the course of their lives.
Don't rob your children. Speak words of blessings over them. Pray the blessings of God upon them. Words are life.
