If we do the best we know how, and yet commit many acts that are wrong and contrary to the counsel given to us, there is hope in our case. 2:132.
CHAPTER XXXVIII
THE TESTIMONY OF THE TRUTH
All Latter-day Saints May Know the Gospel Is True—It is a special privilege and blessing of the holy Gospel to every true believer, to know the truth for himself. 1:234.
It is both the duty and privilege of the Latter-day Saints to know that their religion is true. 8:148.
We are the witnesses of this great work which the Lord has commenced in the latter days. 11:213.
Let every one get a knowledge for himself that this work is true. We do not want you to say that it is true until you know that it is; and if you know it, that knowledge is as good to you as though the Lord came down and told you. 8:142.
There is not a man or a woman on this earth who receives the spirit of the Gospel but what can testify to its truth. 11:213.
We must have the testimony of the Lord Jesus to enable us to discern between truth and error, light and darkness, him who is of God, and him who is not of God, and to know how to place everything where it belongs. That is the only way to be a scientific Christian; there is no other method or process which will actually school a person so that he can become a Saint of God, and prepare him for a celestial glory; he must have within him the testimony of the spirit of the Gospel. 3:155.
If you are satisfied, in your sensitive powers and faculties, that God has revealed the holy Priesthood, established his Kingdom upon the earth, restored the fulness of the Gospel, and set his hand to gather the House of Israel, this will answer your purpose just as well as though you went into heaven to see for yourselves. 8:261.
