Did Esau's tears change his standing before God?

No. Esau's weeping and tears did not change his standing before God or his status in faith. Although he sought the blessing with tears, he did not turn to believe God or become a man of faith. Emotional grief alone cannot alter one's spiritual position before God.

Les explains that Esau lifted up his voice and wept, and this is what Hebrews meant when it says he sought the blessing with tears. Yet in spite of all the weeping, wailing, crying, and tear-shedding, Esau's status in faith did not change one bit. He did not come out of the experience saying he would believe what God says or become a man of faith. Les applies this to emotionalism, warning that people can be forced by emotion to do things they do not really mean, and that God opens hearts, which may take time.

Did Esau's weeping over the lost blessing change his spiritual standing?

Esau's weeping over the lost blessing did not change his spiritual standing at all. Though he sought it with tears, he did not respond by believing what God says or becoming a man of faith. Emotional grief and wailing alone produced no change in his status in faith.
