3rd Nephi 9-13
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; And if it so be that the church is built upon my gospel then will the Father show forth his own works in it. 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 hewn down and cast into the fire, from whence there is no return. For their works do follow them, for it is because of their works that they are hewn down; therefore remember the things that I have told you. Behold I have given unto you my gospel, and this is the gospel which I have given unto you—that I came into the world to do the will of my Father, because my Father sent me.
When you are looking for a church, you need to pray and study to find the truth. There are several churches out there that say they are the true church, but only one can be 100% true. When you are learning and listing to the preaching, see if it matches the scriptures completely. Only Christ’s true church will match 100%. If there is anything added or missing that church is not of Christ. That does not mean that there are not God fearing people in that church trying their best, but it means that they are not following the truth completely. Please study and pray and God will give you your answer.
