How to Become a Celestial Being

In a D&D-like game that I'm running for myself, the main character, a paladin named Eloise, has a goal of becoming a Celestial Being. Yet, she has some doubts about whether she can accomplish that feat. She sees herself as being too flawed, too human, to become Celestial. She shared these concerns with an NPC name Saint Halcion, who had been human and who had since become an angel, and he offered her these words of comfort and advice: 

One need not be perfect in order to be good, and one need not be perfect in order to rightly be called Celestial. Continue working on your flaws always, but you will become a Celestial Being long before you become perfect.

Granted, I was writing both of these characters, so this was really just me talking to myself, but even so, I think this advice is worth considering. We're not perfect, and we're not going to become perfect in this lifetime. We won't be perfect by the time of Final Judgement, but that's okay; we don't have to be. One does not need to be literally perfect to qualify for the Celestial Kingdom, and our Eternal Progression will continue long after we get there. Like Saint Halcion said, we will become Celestial Beings long before we become perfect. In fact, in terms of our behavior, we can become Celestial now. We can uphold Celestial standards, even in mortality, even as we continue to fall short of perfection.

None of us is perfect. None of us will become perfect in this lifetime. But we can be good, we can be Celestial, and we can gradually, eventually become perfect, especially if we work on overcoming our flaws and being good, rather than worrying that we might not be good enough.
