We are asked to define what we mean by one-idea ism, and explain to us how the universe is made up of atoms. With this request we will cheerfully comply. It is to be carried away with one idea. The idea may be a good one, or it may not; but one-ideaism, is giving an idea undue importance. A man addicted to one-ideaism, can no more cover it than a leopard can change his spots. If he attempts to pray, he will commence with something else as a stepping stone, regularly paving the way and unmistakably making his way to his favorite idea. When it is put forth and he is delivered of it he is relieved for the time being, especially, if he finds that it annoys some one. If you call on him for an exhortation, a sermon, or if he writes, he may wind round and round, trace back and forward, but it will, in spite of himself, in all his efforts to conceal it, be manifest to all, that he takes no interest in all he is saying, only as it subserves his purpose, in paving the way to the one idea, the center around which the whole man revolves, and to which his entire existence is subservient. If that one idea is not dragged in, the man is not relieved, his burden is still upon his soul, and he is in travail waiting to be relieved. You will see this class of men at meetings, and conventions, both political and religious, without the most distant idea of promoting the objects of the meeting, convention, etc., as the case may be, but with no higher aim than introducing their idea to notice, making the meeting an engine, and men, met under other obligations, and with the ostensible object of the meeting before them, instruments to carry the _pet idea_ on the high road to fame. Sometimes this class of men, because other men have other objects in view, are actually engaged in some good and great work, have not time, will not be annoyed nor turned aside to hear them nor dispute with them; or, if they do, give them but a passing notice—think all the world afraid of them. But they need have no fears on this score. An idea that has not force enough to burst its way forth in the world in defiance of all fogies and conservatives, would die a natural death, if the parent of it could get some one to bring it forth. MINISTERING ANGELS. We have much in the present day on the spiritual care which the divine Father exercises over his creatures in this world. We consider it clear that God has angels who guard, protect, and take care of that portion of the human family which put their trust in him. That the first Christians believed that a good man had an angel, is clear, from Acts xii. 15. When the Apostle Peter was delivered from prison by a miracle, and his voice was heard at the gate, where several disciples were collected, they could not believe it was him, but said, “_It is his angel_.”
