Genesis 27:36
36 And he said, Is not he rightly named Jacob? for he hath supplanted me these two times: he took away my birthright; and, behold, now he hath taken away my blessing. And he said, Hast thou not reserved a blessing for me?
When I got home from work today, I was met by my 1 year old son holding an apple that was almost as big as his head. I noticed he had dropped it on the floor because it was dirty. I took the apple from him and was going to peel him another one. Chaos immediately erupted and I was chased through my house by a 1 year old child determined to get his apple back. That determination is what Christians need to have when the enemy tries to take your blessing. Just like the little knee-high child, get to the point that when the enemy tries to take what God has blessed you, chase him down and take it back.
