Brigham Young on getting into the Celestial Kingdom

When we get before father Adam and the innumerable company that will come before him-when we draw near to the Ancient of Days with the rest of his children, and receive his approbation, shall we not be safe? If we can pass the sentinel Joseph the Prophet, we shall go into the celestial kingdom, and not a man can injure us. If he says, "God bless you, come along here;" if we will live so that Joseph will justify us, and say, "Here am I, brethren," we shall pass every sentinel; there will be no danger but that we will pass into the celestial kingdom. Will we all become Gods, and be crowned kings? No, my brethren, there will be millions on millions, even the greater party of the celestial world, who will not be capable of a fulness of that glory, immortality, eternal lives and a continuation of them, yet they will go into the celestial kingdom. Will this people all go into that kingdom? I think a good many will have to be burnt out like an old pipe, before they can go into any decent kingdom.   

Think how many have come into this church, from the commencement of it until now, and apostatized. Will our present population equal them in number? No, it would be like a drop in a bucket, compared with them. Do you know of any other people's striving to enter in at the strait gate besides this people? Yes, many in the sectarian world, and the honest among the heathen nations are seeking with all their mights to enter in, and I do not know but what they are the foolish virgins that brother Hyde has been talking about. The parable will apply to them, as well as to a portion of this people. They live according to the moral law given to them, and no people can be morally any better than are thousands and millions of them, for they have spent days and years on their knees to get the power we have, but could not obtain it. Why? Because they had not the keys of the everlasting Priesthood. Where will they go? To heaven, and they will have all the heaven, bliss, and crowns that they have anticipated in the flesh, and then you may add a hundred fold more. Can they go into the celestial kingdom? No, not without the keys of that kingdom.   

 
Well, brethren and sisters, may the Lord bless you and comfort your hearts. Be true to your God and to your religion. Do not forsake them, but forsake sin wherever you may see it. Shun sin, whether it is in me or in any other person, and cleave to righteousness and to the Lord. Do not betray your God nor your covenants, and I say, God bless you and prepare us all for His celestial kingdom. Amen.
