THE DOCTRINE AND COVENANTS OF THE CHURCH OF JESUS CHRIST OF LATTER-DAY SAINTS
26 And in athat day shall be heard of bwars and rumors of wars, and the whole earth shall be in commotion, and men’s hearts shall cfail them, and they shall say that Christ ddelayeth his coming until the end of the earth.
27 And the alove of men shall wax cold, and biniquity shall abound.
28 And when the times of the aGentiles is come in, a blight shall break forth among them that sit in darkness, and it shall be the fulness of my cgospel;
29 But they areceive it not; for they perceive not the light, and they turn their bhearts from me because of the cprecepts of men.
30 And in that generation shall the atimes of the Gentiles be fulfilled.
We are in the "times of the Gentiles." Jesus reestablished His Gospel in this, the fullness of times. Joseph Smith has received the revelations from Jesus and from the other messengers sent from His presence to restore the truth and the authority to the earth. How do I know? How can you know? Only by the revelation of the Holy Spirit. It is the Spirit's purpose to testify of truth and to testify of the Son. By prayer, pondering, faith and fasting, one can come to know of the truthfulness of all things.
