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 on the word of Christ, and endure to the end, behold, thus saith the Father: Ye shall have eternal life.
And now, behold, my beloved brethren, this is the way; and there is none other way nor name given under heaven whereby man can be saved in the kingdom of God.
2 Nephi 31:20-21
This idea of ‘enduring to the end’ is hard. Because it’s not ‘enduring until your difficult experience is over’, or ‘until the good things start again’, (which are hard enough), but forever – to the end! One has to keep working, hard, all the time; it won’t stop being necessary. You have to keep at your good habits and discipline, and denying yourself indulgence and laziness and fear, all the way. You can’t leave off when things start going better for you; doing the right things has to be what you always do, or stuff will be harder again. You can’t ever give up. You can’t ever take it easy. Enduring is for always. And that’s really tough.
