Interesting article, I hope it’s true. I will say this however, I have seen way too many parents, Christians, out and out fail to provide for their children and claim it is fine. It is not fine.
I have said that Abraham possessed nothing. Yet was not this poor man rich? Everything he had owned before was his still to enjoy: sheep, camels, herds, and goods of every sort. He had also his wife and his friends, and best of all he had his son Isaac safe by his side. He had everything, but he possessed nothing. There is the spiritual secret. There is the sweet theology of the heart which can be learned only in the school of renunciation. The books on systematic theology overlook this, but the wise will understand. I don't think that Tozer was meaning not owning anything nor passing down an inheritance to one's children.
I think what he meant was that in Abraham's heart, he owned nothing of this world. That he would have given it all up as it had no hold on him.
Perhaps it would be better said that the world did not own Abraham.
