Almighty God says, "Those who have been perfected are not just able to achieve obedience after being conquered, but they are also able to have knowledge of the work of judgment, change their disposition, and know God. They experience the path of loving God and are filled with the truth. They know how to experience God’s work, are able to suffer for God, and have their own wills. …The perfected refers to those who, after the conquering work ends, are able to pursue the truth and be gained by God. It refers to those who, after the conquering work ends, stand firm in tribulation and live out the truth."
