But of course, that would never happen. The X-Men would never give up in the middle of a fight! (Not even Cyclops... though he'd be the most likely). They're going to see it through to the bitter end, no matter what happens. Nothing would stop them from defending the innocent and upholding justice. That's what they do, that's why they're the X-Men. They're there through thick and thin, and are going to make sure the job gets done.
We're all here to be tested. Just like the prophet Alma taught, "For behold, this life is the time for men to prepare to meet God; yea, behold the day of this life is the day for men to perform their labors." (Alma 34:32). We are meant to prepare for that time when we stand before the Lord to be judged. Imagine what it would be like to get up there and have to tell your Heavenly Father "Well, I got really tired, and that seemed like it would be really fun, so I decided to just go for it." That probably wouldn't go over very well, would it? Just because it's hard to get up and go to church, or you're really tired and don't feel like reading your scriptures, or your friends keep telling you one little drink won't hurt doesn't mean that you can just give up. Once you know who you are and see the path laid ahead of you, it's Exaltation or bust... and that all depends on you. Endure to the End! Live the life you know you should live. Enduring to the End is just constantly redoing those previous steps: It's always having faith in Jesus Christ and in your Heavenly Father, it's constantly repenting and making yourself better, it's living worthily to take the sacrament and renew the covenants you made at baptism, and it's striving to constantly have the Holy Ghost with you. It seems to me that this step is either the easiest or the hardest, and you're the one that makes it that way.
