The continued daily sacrifice of animals in the Old Testament was intended to sanctify the heart of man. This is no longer necessary because of the sacrifice of Jesus on the cross. The blood of Jesus is our constant seal against the sinful fleshly nature. When we pray, we must have a single mind; the mind must remain focused on God’s supply. However, the thought life is always under attack from the flesh as worry or stress enters the mind; our prayers are powerless. The blood of Jesus cleanses and seals the conscience against the coming and going of the fleshly chaos.
I meet so many believers who do not get their prayers answered. They pray, and when they do not get heavenly help, they give up and live in poverty. They are believers, but they have no testimony of how God provides.
My mother was the spiritual leader in our home, as my father had no respect for preachers or churches. We were a big family, and when anything went wrong, I would hear my mother calling upon the blood of Jesus over her family from her bedroom. Nothing bad ever happened to our family, even until today, because she made sure we understood the power of the blood. She did not understand the blood, but she applied it constantly because she knew it was all-powerful. She was a normal person and not completely spiritually minded and would do and say silly things as we all do, but when trouble came, she knew the power of the blood of Jesus gave her the right to have faith for anything she needed. She would use her faith and would cause incredible miracles.

I am saying these things to remind our readers that we cannot have confidence to move our mountains if we are not sanctified and sealed with the blood of Jesus. The blood is for the conscience. The blood-washed conscience gives us the confidence to stand before all of heaven to claim the things we have need of. I am saying that whatever we truly need will be supplied by heaven if we pray with the faith that is only in a sanctified heart. Sometimes we pray for things half-heartedly; we put the prayer out there and hope God will give it. You must admit, most of our prayers are like that. It causes us to be powerless believers without a testimony of the provision of God.
In Revelation 12, we read how the holy ones of God overcome the enemy by the blood of the lamb and the word of their testimony. We can really only help each other by our testimonies.
Rev 12:11: “And they overcame him (the enemy) by the blood of the Lamb, and by the word of their testimony; and they loved not their lives unto the death. Some people are afraid to keep on praying because they are afraid the devil will turn against them; they are not bold and ready to stand against the satanic onslaught because they do not know the power of the cross and the blood. They have more faith in the devil than they have in God.
But are we really the holy ones of God?
Is the Bible talking about us today? Yes! Most certainly, when we have communion and follow Jesus to lay down our lives and apply the blood of the Lamb of God to our hearts, our sins are forgiven, and we are the holy ones to whom all of heaven listens intensely. Many of my personal prayers have gone unanswered, but when I truly have need of heavenly intervention, God has always met my need.
We need not fear the future and the bad that comes with it. No matter what happens, God will always answer our prayers if we pray from a sanctified heart.
