Yahushua narrated the parable of the ten hired bride/groom's maids. Five of them were unwise in their decisions and five among them were wise in their decisions. The difference is that the wise ones planned ahead and took extra oil for their lamps to last till the bride and groom arrive home for the wedding festivities. The unwise maids/servants did not plan ahead for the event. Perhaps for lack of understanding of the magnitude of the occasion that they were hired to be part of. The chosen ones of our God need extra oil or understanding of what is required of them, where? and when? by the groom at his return home. In this book, "Extra Oil for Your Lamps..." you will find extra oil/knowledge for your spiritual lamps to keep the light in you from turning into darkness at the unexpected hour of the final test.Revelation 2:10, 3:10. The hour of final test foretold to come upon those dwelling on the earth is almost here. Only those with extra oil/knowledge of what is really taking place, those taught by Yahuwah the living God will endure to the end and be preserved into the new world to come. Therefore, buy wisdom/oil and sell it not. Only unwise ones will despite knowledge.
