Yet God has given us the tools or weapons of warfare to stop a generational curse. You will find the answers in the word of God. For starters, 2 Corinthians 10:3-4
"For though we live in the world, we do not wage war as the world does. The weapons we fight with are not the weapons of the world. On the contary, they have divine power to demolish strongholds."
We must learn how to use these weapons. Our descendents depend upon it.
