says, "God of the last days principally uses the word to make man perfect. He does not use signs and wonders to oppress man, or convince man; this cannot make plain the power of God. If God only showed signs and wonders, then it would be impossible to make plain the reality of God, and thus impossible to make man perfect. God does not make man perfect by signs and wonders, but uses the word to water and shepherd man, after which is achieved the complete obedience of man and man’s knowledge of God. This is the aim of the work He does and the words He speaks. God does not use the method of showing signs and wonders to make man perfect—He uses words, and uses many different methods of work to make man perfect. Whether it be the refinement, dealing, pruning, or provision of words, God speaks from many different perspectives to make man perfect, and to give man a greater knowledge of the work, wisdom and wondrousness of God. When man is made complete at the time that God concludes the age in the last days, he will be qualified to look upon signs and wonders. … The time that God shows signs and wonders is when God punishes man, and also when the age changes, and, moreover, when the age concludes. When God’s work is being carried out normally, He does not show signs and wonders."
