Genesis 27:26-33 (ESV)

Then his father Isaac said to him, “Come near and kiss me, my son.” So he came near and kissed him. And Isaac smelled the smell of his garments and blessed him and said, “See, the smell of my son is as the smell of a field that the LORD has blessed! May God give you of the dew of heaven and of the fatness of the earth and plenty of grain and wine. Let peoples serve you, and nations bow down to you. Be lord over your brothers, and may your mother's sons bow down to you. Cursed be everyone who curses you, and blessed be everyone who blesses you!”

As soon as Isaac had finished blessing Jacob, when Jacob had scarcely gone out from the presence of Isaac his father, Esau his brother came in from his hunting. He also prepared delicious food and brought it to his father. And he said to his father, “Let my father arise and eat of his son's game, that you may bless me.” His father Isaac said to him, “Who are you?” He answered, “I am your son, your firstborn, Esau.” Then Isaac trembled very violently and said, “Who was it then that hunted game and brought it to me, and I ate it all before you came, and I have blessed him? Yes, and he shall be blessed.”

Isaac’s blessing of Jacob conveys real consequences – and it seems to be irrevocable. How?

The Bible doesn’t explain how Isaac’s words have such power, but the power must come from God. Isaac’s blessing has to be just an effectual prayer.

But the irrevocable bit is more difficult. Are some prayers cast in stone? That seems unlikely given that even God’s own pronouncements can be revoked (e.g., Jonah 3:1-10). So, how come this one is irrevocable?

Actually, the Bible doesn’t say that it is. Isaac thinks it’s irrevocable and so won’t revoke it. Scripture doesn’t have any divine instructions about “blessing law,” so Isaac seems to just be following tradition.

Remember, this is before any mass communication; everything Isaac knows he heard word-of-mouth. To know that a blessing can’t be revoked, even if given under false pretenses, he would have to know of a special rule or at least a similar case.

Neither is mentioned in scripture.

Imagine how tragic it would be if God didn’t edit our prayers. We’ve all made amusing goofs while on our knees. We mistake names, places, goals, even God’s priorities.

But it’s all OK, even glorifying. God does wondrous things in response to fumbled prayers. Our prayers aren’t really all that different from the bedtime prayers of a child – and they’re just as beautiful.

Spend some time thinking about the simplest prayers we say, the ones we teach our children, the prayers we say before eating.

They matter.
