I recollect a dream that my father had. He dreamed that he was travelling, and that during his journey he came to a tremendous mountain of snow and saw that his pathway was hedged up. But some one said, “Take one more step.” My father replied, “But that will be the last.” However, he took that step, and then his guide said, “Do you not, see that there is room for you to take another?” When he had taken another, his guide told him to take still another in advance; and there was a passage all the way through. So it will be with us. The Lord will not reveal all that we at times wish him to. If a schoolmaster were to undertake to teach a little child algebra, you would call him foolish, would you not? Just so with our Father: he reveals to us as we are prepared to receive, and I hope to continue to learn. There is no cessation, in time nor in eternity, to the progress and increase of the righteous. If we will but put away every selfish feeling, we can come in possession of all the blessings that are in store for us.
