Do you appreciate the fact that you could die any time and meet God? So isn’t it wise for you to accept Christ’s gospel and repent of your sins and pray and go to Church and read the scriptures and get ready? (Just a couple of thoughts for your consideration. Richard W. Linford, editor.)
The gospel of Jesus Christ is found in the Book of Mormon, 3 Nephi 27:
8 And how be it amy bchurch save it be called in my name? For if a church be called in Moses’ name then it be Moses’ church; or if it be called in the name of a man then it be the church of a man; but if it be called in my name then it is my church, if it so be that they are built upon my gospel.
9 Verily I say unto you, that ye are built upon my gospel; therefore ye shall call whatsoever things ye do call, in my name; therefore if ye call upon the Father, for the church, if it be in my name the Father will hear you;
10 And if it so be that the church is built upon my gospel then will the Father show forth his own works in it.
11 But if it be not built upon my gospel, and is built upon the works of men, or upon the works of the devil, verily I say unto you they have joy in their works for a season, and by and by the end cometh, and they are ahewn down and cast into the bfire, from whence there is no return.
12 For their works do afollow them, for it is because of their works that they are hewn down; therefore remember the things that I have told you.
14 And my Father sent me that I might be alifted up upon the bcross; and after that I had been lifted up upon the ccross, that I might ddraw all men unto me, that as I have been lifted up by men even so should men be lifted up by the Father, to stand before me, to be ejudged of their works, whether they be good or whether they be evil—
16 And it shall come to pass, that whoso arepenteth and is baptized in my bname shall be filled; and if he cendureth to the end, behold, him will I hold guiltless before my Father at that day when I shall stand to judge the world.
17 And he that endureth not unto the end, the same is he that is also hewn down and cast into the fire, from whence they can no more return, because of the ajustice of the Father.
18 And this is the word which he hath given unto the children of men. And for this cause he fulfilleth the words which he hath given, and he lieth not, but fulfilleth all his words.
19 And ano unclean thing can enter into his kingdom; therefore nothing entereth into his brest save it be those who have cwashed their garments in my blood, because of their faith, and the repentance of all their sins, and their faithfulness unto the end.
20 Now this is the commandment: aRepent, all ye ends of the earth, and come unto me and be bbaptized in my name, that ye may be csanctified by the reception of the Holy Ghost, that ye may stand dspotless before me at the last day.
21 Verily, verily, I say unto you, this is my agospel; and ye know the things that ye must bdo in my church; for the works which ye have seen me do that shall ye also do; for that which ye have seen me do even that shall ye do;
22 Therefore, if ye do these things blessed are ye, for ye shall be lifted up at the last day.
Preparation for the Second Coming is found in living according to the Ten Commandments (Exodus 20: https://www.churchofjesuschrist.org/study/scriptures/ot/ex/20?lang=eng ) and Beatitudes (Matthew 5: https://www.churchofjesuschrist.org/study/scriptures/nt/matt/5?lang=eng) found in the Old Testament and New Testament respectively.
