who are always there to support the work of god and 
for their great blessings
Exodus 20:5;
5 do not you laning in front of them or worship them. I, the Lord your God, am a jealous God. When parents are evil and hate me, I punish their children unto the third and fourth generation.
Exodus 34:7;
7 which maintains his love up to one thousand generations later, and which forgives wickedness, rebellion and Sin; but that does not leave the guilty unpunished, but punishes the iniquity of the fathers on the children and grandchildren, to the third and the fourth generation.
Numbers 14:18;
18 that you are slow to anger and great in love, and that even if you forgive the wickedness and rebellion, never leave unpunished criminals, but you punish the iniquity of the fathers on their children, grandchildren, great-grandchildren and grandchildren.
Deuteronomy 5:9
9 do not you leaning in front of them or worship them. I, the Lord your God, am a jealous God. When parents are evil and hate me, I punish their children unto the third and fourth generation.
It seems unfair for God to punish children for the sins of their parents. However, this is looking at it from an earthly perspective. God knows that the effects of Sin are transmitted from one generation to the next. When a parent has a sinful lifestyle, their children are likely to have the same sinful lifestyle also. Therefore, it is not unjust for God to punish without to the third or fourth generation - because they commit the same sins their ancestors did. But they are punished for their own sins, not the sins of their ancestors. The Bible specifically tells us that Dios not responsible to children for the sins of their fathers
Deuteronomio 24:16
16 will not be death to parents because of their children, nor will be death to the children because of their parents. Every one shall die for his own sin.
AS BREAK OR CANCEL A CURSE
2nd Chronicles
30:7 do not be as your fathers and your brothers, who rebelled against the Lord God of their fathers, and he gave them up to desolation, as ye see.
30:8 do not harden, so now your cervix as your fathers; Submit yourselves unto the Lord, and come to his sanctuary, which he has sanctified forever; and serve the Lord your God, and the fierce anger will turn away from you.
To break the curse of a life, you need someone who knows and know about spiritual matters. Not anyone can break a curse, is must seek help from someone understood and with spiritual authority to deal with the demons, so that advice on what and how to do it. Also the person must prepare and be strengthened spiritually to the battle for his release and his family
In a nutshell: break or cancel a curse has to do with out the demons and shut the door behind, so that not to enter.
Do not return to Sin so that does not happen something worse.
Forgive those who did us harm and ask forgiveness for them. This is more difficult but not impossible, to do it.
Cry out for the release of related persons.
Likely spiritual warfare, battles with various demons who do not want to release the family.
Should be strengthened in the power of the Holy Spirit, filled with their presence and let it flow.
Follow faithfully to God, without deviating to the left or right hand.
There is no curse that cannot be cut or break, who then gives the last word is God and there is nothing greater or stronger than the power and the sovereignty of God. Any person (whatever your spirituality and faith), it can and it must rely on the power of God to be free. How much closer we are to God, further will be curses (i.e. demons) of our life.
Indicated more is to seek the help of spiritual authorities (Apostles, evangelists, prophets, pastors, teachers) for counselling and ministration, and count on the body of Christian warriors intercessory prayer. God, with his infinite love and power, can make a person free of curses in an instant, with an only miracle, but that depends on each case and of your divine will. It is also very possible that someone receives revelation directly from the Holy Spirit, also must rely on the spiritual support of the Church to resolve the case. There are battles of great magnitude, no one will be lonely super-hero-Christian, we all need support and backing of the prayer of our brothers.
STEPS FOR RELEASE OF CURSE
James 4:7
Submit yourselves, then, to God. Resist the devil and he will flee from you.
Every effect has a cause and we know that all curse has a cause. The first thing that must be done is to identify and define the problem, this is accomplished by examining in detail the effects and consequences, all that is seen and all palpable but with spiritual insight very keen, well awake not to fall into the deception of the demons.
The entire process of counselling and ministration of the person wanting to be free of curses should be supported all the time of communion and the revelation of the Holy Spirit, this means that a spiritual work can never be based on carnality or in the physical world, or psychology, or studies only, the Holy Spirit is who will do the work and will give indications, we the Ministers are only partners, intermediaries and interpreters. Ministers must put all their knowledge and spiritual preparation services of the Holy Spirit, to make it work as expected. Also each person wishing to achieve this freedom and victory in God, must also collaborate with its instructions and be faithful to the commandment. To God be the glory. Amen.
Genesis 17:7
And I will establish my Covenant between me and you, and your offspring after you in their generations, by agreement perpetuo, to be your God, and your offspring after you.
