Eugen von Böhm-Bawerk
He has told us everything the Father has told him and left the Holy Spirit to remind us and guide us. He is not playing Russian Roulette with us. We do not know when the end will come - when he will come down in Glory to judge the living and the dead and we do not know exactly when we will die as death will come as a thief in the night, but, we know a lot. We do not know everything and much has been left a mystery - but, we know plenty.
