Sacrifice is what releases power. 
Sacrifice is the food for spirits, they can never be appeased without it. 
A sacrifice leads to a divine encounter, which results in changes. 
When you tie your expectations to sacrifice it shows that you believe God 
You cannot sacrifice something you don’t love, such a sacrifice would be unacceptable. 
Genesis 22:2
In sacrifice you substitute your weakness for God’s strength. 
Some things will only go out though sacrifice. 
Resurrection power is the highest power, and it came about through sacrifice. (Philippians 2:9)
Where there’s no sacrifice there’s no real power. 
No witch has power to release enchantments against anybody without making sacrifices to a deity in order to release power to enforce those enchantments. 
Psalm 91:1-5, 14
Your exemption doesn’t lie in your status but in your active partnership with God.
