A carnal mind wants God to bring the birthright down to their level. But for me, and I believe all true born Christians, we meet it on God's level. I don't care what I have to do, or what I have to say, how I have to act: the only thing, I want it. That's means more than my popularity. That means more than my job. It means more than my mother, means more than my wife, more than my children, more than every friend I got. Let me have that birthright. I don't care what I have to pay. I want to meet God on His requirement. Whatever He requires, if it's fall in dust, if it's speak with tongues, if it's run through the building and act like a maniac, or stand on my head, I don't care what it is, just so I get it. That's the main thing. That's the spiritual minded people. They want the birthright, regardless.
They want it. And as soon as they get it, it sets up the same reaction it was in that family. Finally, it'll come to a place till there come a separation. A man will have to obtain, if he obtains this birthright, he will have to separate himself from the world, just as Jacob had to.

My, sometimes it means walk alone. But if you really are sincere, and you really receive the birthright, you don't care to walk alone. If the neighbors won't invite you anymore over to dinner, if nobody will have anything to do with you, what difference does it make to you? As long as you've got the birthright, that's the main achievement of your life. As long as I'm borned of the Holy Spirit, what difference does it make? Long as I'm on my road to heaven, what difference does it make what the people say as long as we're walking in the Spirit? And all that's borned of the Spirit of God, are led by the Spirit of God. Sons and daughters of God are led by the Spirit of God, always walking in the beautiful light of holiness, cleanliness.
But Esau, that birthright... He was carnal like the world, so it didn't make any difference to him. He thought he was religious, and his papa and mama was religious, and that was good enough for him.
