Genesis 27:26-27, 29 NKJV
 Then his father Isaac said to him, “Come near now and kiss me, my son.”
 And he came near and kissed him; and he smelled the smell of his clothing, and blessed him and said: “Surely, the smell of my son Is like the smell of a field Which the LORD has blessed.
 Let peoples serve you, And nations bow down to you. Be master over your brethren, And let your mother’s sons bow down to you. Cursed be everyone who curses you, And blessed be those who bless you!”
Shortly after receiving the Blessing and he had packed the plates of the food from the stool before his father, Esau walked inside with his hot savoury meat for his father. And upon hearing that his brother had came in and craftily taken his place and received all the Blessing reserved for him, he burst into tears and wept bitterly.
That spirit of deception and craftiness was an Anakim, a great Giant, in the life of Jacob. And the Giant kept showing up in his life to give him series of setbacks in life till the Giant manifested in his next generation. This spirit of Deception and Falsehood manifested as a terrible Giant that possessed his sons too.
Genesis 37:31-35 NKJV
 So they took Joseph’s tunic, killed a kid of the goats, and dipped the tunic in the blood.
 Then they sent the tunic of many colors, and they brought it to their father and said, “We have found this. Do you know whether it is your son’s tunic or not?”
 And he recognized it and said, “It is my son’s tunic. A wild beast has devoured him. Without doubt Joseph is torn to pieces.”
 Then Jacob tore his clothes, put sackcloth on his waist, and mourned for his son many days.
THE SPIRIT OF DECEPTION AND FALSEHOOD APPEARED IN THE LIFE OF HIS SONS TOO. He was greviously deceived by the tunic of his son dipped in an animal blood, and he wept bitterly as his brother Esau also wept bitterly when he (Jabob) decieved his brother Esau several years back. He suffered for many years mourning the death of his living son.
When a man is full of lies and he refuses to deal with that spirit, though he is not a lustful or immoral person, the Spirit of Lies is the Giant he has not conquered, that may resurfaces in the lives of his children.
When a woman is so arrogant and proud, and she does not deal with the spirit of Pride and Arrogance, even though she is very prayerful and dedicated to the church and the things of the ministry, that spirit of Pride and Arrogance become a Giant in her life that may go ahead to reflect in the life of her children.
Therefore, it is not enough to take the land of your Callings and Ministry, without dealing with the stubborn characters and habits of your life that may become a Giant that would reflect upon your seeds later in life.
Some ministers may be doing well in their ministries presently; their ratings are rising before people; a lot of people are getting blessed through their various ministrations, music and movies, but, if there is the Spirit of Greed and Covetuousness that a lot of people have been noticing in your lives, that must be dealt with now, it has to be dealt with as soon as possible or it would pass over to begin to reflect upon their children and spiritual seeds as reoccurring Giants.
If the spirit of immorality and lists have not been dealt with in a person’s life and he continues living his life without paying attention to the spiritual dent, it would begin to resurface in the lives of his spiritual and biological seeds.
Have you noticed that if a particular man of God is your mentor and father-in-the-Lord, and you submit yourself to him and stays under him as your father, sooner, his traces will begin to manifest in your life and habits. If he is a materialistic minister of God, sooner, you too will begin to do whatever he does. If he is a faith or Mission-minded person, it will soon begin to show up on you. THAT IS THE MANIFESTATIONS OF THE GIANTS OF YOUR FATHER.
As you go on fighting and taking the land of Great Exploits and mighty visions, kill all the Kings and spare not the Giants of the land. Deal with all sins and ungodly habits of our life so that they will not begin to gather to manifest in your biological and spiritual sons.
