Uncertainty is familiar to you all. If you knew everything, you would stagnate and there would be no incentive to act. But it is only through activity, soul activity, that you can find your way back to God. Uncertainty is, therefore, a necessity of life and it should make you look inside, outside, and look all round you, so that you can assess the situation. You then become curious, and wonder what is going to happen. (NNSG Vol.3, p. 119)
