Endure in Faith - D&C 20:25

That as many as would believe and be baptized in his holy name, and endure in faith to the end, should be saved

 Enduring to the end is a theme that is touched upon several times in scripture. Consider the following:

Wherefore, ye must press forward with a steadfastness in Christ, having a perfect brightness of hope, and a love of God and of all men. Wherefore, if ye shall press forward, feasting upon the word of Christ, and endure to the end, behold, thus saith the Father: Ye shall have eternal life. (2 Nephi 31:20)

And moreover, I would desire that ye should consider on the blessed and happy state of those that keep the commandments of God. For behold, they are blessed in all things, both temporal and spiritual; and if they hold out faithful to the end they are received into heaven, that thereby they may dwell with God in a state of never-ending happiness. O remember, remember that these things are true; for the Lord God hath spoken it. (Mosiah 2:41)

Brigham Young urged us to view endurance in the proper perspective. It is not a long drudgerous slog to the end, but a time of preparation for exciting things in the beyond.

We are urged by the Spirit to refrain from articles which tend to death, to preserve this life, which is the most precious life given to mortal beings preparatory to an immortal life. It is our business to prepare to live here to do good. Instead of crying to the people, prepare to die, our cry is, prepare to live forever. (DBY)

 Joseph Smith gave the following insight:

Whatever principle of intelligence we attain unto in this life, it will rise with us in the resurrection. And if a person gains more knowledge and intelligence in this life through his diligence and obedience than another, he will have so much the advantage in the world to come. (D&C 130:18-19)

It is best to view this life as a laboratory in which the environment is adjusted just right so as to enable us to progress at an accelerated rate. We do not know what awaits us in the eternities, but the here and now are for our progression, gathering of knowledge, wisdom and experience to enable us with a head start in the eternities. But we must stay true and faithful, doing good as much as we can, and correcting our mistakes through repentance and the grace of the Lord Jesus Christ as we go along.

The sin that will cleave to all the posterity of Adam and Eve is, that they have not done as well as they knew how. (DBY)
