The Gospel is Preached With Authority—When a man who is called and ordained of God goes forth he preaches the ordinances, faith in Christ and obedience to him as our Savior. He declares that the first step to be taken, after believing in the Father and the Son, is to go down into the waters of baptism and there be immersed in the water, and come up out of the water as Jesus did. Some may inquire why the Latter-day Saints are so strenuous on this point? We do it for the remission of sins; Jesus did this to fulfil all righteousness. 14:96.
Perhaps some may say that I have too much faith in the prophecies of God, in the latter-day work, and in the administration of individuals that now live and have lived on the earth in our day. Be it so, no matter to me. I am here to testify in the name of the God of Israel that for many years past there have been men traveling through the length and breadth of the earth who possess the same power and authority as that with which Jesus endowed his Apostles when he told them to go into all the world and "preach the Gospel to every creature, and he that believeth and is baptized shall be saved, but he that believeth not shall be damned, and these signs shall follow them that believe. In my name they shall cast out devils, heal the sick, speak with new tongues," etc. 14:131.
The Spirit, Not Logic or Debate, Makes Converts—Let one go forth who is careful to prove logically all he says by numerous quotations from the revelations, and let another travel with him who can say, by the power of the Holy Ghost, Thus saith the Lord, and tell what the people should believe—what they should do—how they should live, and teach them to yield to the principles of salvation,—though he may not be capable of producing a single logical argument, though he may tremble under a sense of his weakness, cleaving to the Lord for strength, as such men generally do, you will invariably find that the man who testifies by the power of the Holy Ghost will convince and gather many more of the honest and upright than will the merely logical reasoner. 8:53.
However good and useful a classical education may be in the possession of a good and wise man, yet it is not essentially necessary for him to have it, to tell the simple truth which is given to mankind by the revelations of God, because it can be told by the simple and the unlearned. 11:215.
Debate and argument have not that saving effect that has testifying to the truth as the Lord reveals it to the Elder by the Spirit. I think you will all agree with me in this; at least, such is my experience. I do not wish to be understood as throwing a straw in the way of the Elders storing their minds with all the arguments they can gather to urge in defense of their religion, nor do I wish to hinder them in the least from learning all they can with regard to religions and governments. The more knowledge the Elders have the better. 8:53.
I had only traveled a short time to testify to the people, before I learned this one fact, that you might prove doctrine from the Bible till doomsday, and it would merely convince a people, but would not convert them. You might read the Bible from Genesis to Revelation, and prove every iota that you advance, and that alone would have no converting influence upon the people. Nothing short of a testimony by the power of the Holy Ghost would bring light and knowledge to them—bring them in their hearts to repentance. Nothing short of that would ever do. You have frequently heard me say that I would rather hear an Elder, either here or in the world, speak only five words accompanied by the power of God, and they would do more good than to hear long sermons without the Spirit. That is true, and we know it. 5:327.
When a false theory has to be maintained, it requires to be set forth with much care; it requires study, and learning, and cunning sophistry to gild over a falsehood and give it the semblance of truth, and make it plausible and congenial to the feelings of the people; but the most simple and unlearned person can tell you the truth. A child can tell you the truth, in child-like language, while falsehood requires the lawyer and the priest to tell it to make it at all plausible; it requires a scholastic education to make falsehood pass for truth. 11:214.
The servants of God have truth, and nothing but truth, to present to the world, that the world may be sanctified by the truth. The truth needeth no polish to make it lovely and desirable to those who love it. 11:234.
They must eventually either acknowledge that he is the Son of God and that his Gospel is the only Gospel, or they must take infidelity. Sooner or later the sects, one after another, will deny the Savior and every one of the ordinances of his Gospel, until they are all enveloped in infidelity, or they must accept the whole. Strange as it may appear, they are now following shadows, phantoms of the brain, and mischievous manifestations. 14:74.
What should the wicked hear? They should hear a man testify that Joseph Smith was and is a Prophet of God, that he was a good man, and that he did plant and establish the Kingdom of God on the earth, and we know it. "How shall I know?" says one. By obeying the commandments given to you. The Lord has said, go into the waters of baptism and be baptized for the remission of your sins, and you shall receive a witness that I am telling you the truth. How? By baptism and the laying on of hands alone? No. By seeing the sick healed? No, but by the Spirit that shall come unto you through obedience, which will make you feel like little children, and cause you to delight in doing good, to love your Father in Heaven and the society of the righteous. Have you malice and wrath then? No, it is taken from you, and you feel like the child in its mother's lap. You will feel kind to your children, to your brothers and sisters, to your parents and neighbors, and to all around you; you will feel a glow, as of fire, burning within you; and if you open your mouths to talk you will declare ideas which you did not formerly think of; they will flow into your mind, even such as you have not thought of for years. The Scriptures will be opened to you, and you will see how clear and reasonable everything is which this or that Elder teaches you. Your hearts will be comforted, you can lie down and sleep in peace, and wake up with feelings as pleasant as the breezes of summer. This is witness to you. 3:211.
