When I was reading the story of Jacob and Esau recently I found it very interesting that God gave them to Isaac and Rebekah when Isaac prayed for his wife as she was unable to have children. God's answer to Isaacs's prayer was twin sons who would continually be in conflict with one another. And not only that when Rebekah wondered what was going on when they were struggling in her womb and asked God about it, he told her that it was Jacob that would inherit the promise from Isaac and not the firstborn Esau. As far as we know from scripture God never tells Isaac that it will be Jacob that is going to inherit the promise, only Rebekah. And when on his death bed Isaac calls for Esau to give him the blessing, it is Rebekah that ensures that it is Jacob that receives the blessing fulfilling what God told her when she was pregnant. Throughout Jacobs's life we continually see that he has to fight for everything that he receives. He has to fight for the blessing from his father that God told his mother he would have, he has to fight to get the wife he wanted after his father in law deceives him when he is getting married. Then when he has worked for free for decades and decides to leave, his father in-law tries to leave him a pauper and he has to fight for the wealth that he receives.
And the most amazing thing about this was that this was the blessing of God on his life. It was because of this continual struggle that in Genesis 32:28 when God comes to him he can struggle with God and prevail becoming no longer Jacob but Israel, the one who fought with God and man and won, the father of the nation of Israel.
We could probably look at David's life and see a similar story. A shepherd boy who was anointed king well before he had any chance of being crowned king, but who became a man after God's own heart and whose son Solomon was the wisest man to have ever lived and who built the first temple of God in Jerusalem.
Accepting the truth that these scriptures reveal to us is not easy. We equate blessing with Joy and happiness and all things nice, not conflict and struggle, not with David fleeing from Saul. But these are part of the blessing of God because of who we will become if we allow God to lead us through them. The blessing is who we will become and it is this goal that God sees.
