Esau - Gen25

Abraham had Ishmael and Isaac; Isaac had Esau and Jacob.
Ishmael and Esau had quite a lot in common.
Esau was very practical, he's a hard worker. He'd trade spiritual things with physical needs if necessary. He didn't esteem the value of his spirutal blessings highly. Like Ishmael, he married a foreign girl.
Jacob, on the contrary, "was a peaceful man, living in tents.(v27)" He's quite laid back, enjoying cooking and just being the mommy's boy. I guess he's a thinker. At times he could be very tricky and sneaky. Although he paid for every bit of tricks and lies later on in his life, he got the most important thing: the bloodline blessing.
Esau worked his way out of the blessing. He took whatever came his way without analysing and seeking the Lord for direction. Sometimes life present us things like opportunity, but by taking these opportunities, we could end up losing every blessing we have in God.
