“Our thoughts are like Jacob and Esau. Spiritual and carnal thoughts struggle together in the same womb. Often the Esau of carnal thoughts will come out first and for a while seem to carry the birthright. But where reverence for God has “cast out the bondwoman and her son” (Gal 4:30), the mind will be free to fix itself on spiritual things.”
-John Owen English Pastor, Theologian 1616-1683
