God says, “When you face suffering, you must be able to lay aside concern for the flesh and to not make complaints against God. When God hides Himself from you, you must be able to have the faith to follow Him, to maintain your previous love without allowing it to falter or dissipate. No matter what God does, you must submit to His design and be prepared to curse your own flesh rather than make complaints against Him. When you are faced with trials, you must satisfy God, though you may weep bitterly or feel reluctant to part with some beloved object. Only this is true love and faith. No matter what your actual stature is, you must first possess both the will to suffer hardship and true faith, and you must also have the will to forsake the flesh. You should be willing to endure personal hardships and suffer losses to your personal interests in order to satisfy God’s will. You must also be capable of feeling regret about yourself in your heart: In the past, you were unable to satisfy God, and now, you can regret yourself. You must not be lacking in any of these regards—it is through these things that God will perfect you. If you cannot meet these criteria, then you cannot be perfected."
