What do you know on natural principles? I do not say natural philosophy, because my religion is natural philosophy. You never heard me preach a doctrine but what has a natural system to it, and, when understood, is as easy to comprehend as that two and two equal four. All the revelations of the Lord Almighty to the children of men, and all revealed doctrines of salvation are upon natural principles, upon natural philosophy. When I use this term, I use it as synonymous with the plan of salvation; natural philosophy is the plan of salvation, and the plan of salvation is natural philosophy. 4:202. Our doctrine and practice is, and I have made it mine through life--to receive truth no matter where it comes from. 14:160. When we demonstrate a truth, we demonstrate a portion of the faith, law, or power by which all intelligent beings exist, whether in heaven or on earth, consequently {17} when we have truth in our possession we have so much of the knowledge of God. I delight in this, because truth is calculated to sustain itself; it is based upon eternal facts and will endure, while all else will, sooner or later, perish. 14:115. All truth is worthy and worth possessing. 19:39. How easy it is to live by the truth. Did you ever think of it, my friends? Did you ever think of it, my brethren and sisters? In every circumstance of life, no matter whether among the humble or lofty, truth is always the surest guide and the easiest to square our lives by. 14:76. Be willing to receive the truth, let it come from whom it may; no difference, not a particle. Just as soon receive the Gospel from Joseph Smith as from Peter, who lived in the days of Jesus. Receive it from one man as soon as another. If God has called an individual and sent him to preach the Gospel that is enough for me to know; it is no matter who it is, all I want is to know the truth. 14:136. All truth is for the salvation of the children of men--for the benefit and learning--for their furtherance in the principles of divine knowledge; and divine knowledge is any matter of fact--truth; and all truth pertains to divinity. 7:284. _We Need a Practical Religion_--I am preaching to you practical religion. 13:155. I am decidedly in favor of practical religion--of everyday useful life. And if I today attend to what devolves upon me to do, and then do that which presents itself tomorrow, and so on, when eternity comes I will be prepared to enter on the things of eternity. But I would not be prepared for that sphere of action, unless I could manage {18} the things that are now within my reach. You must all learn to do this. 5:3.
