People go through lots of changes, sometimes in a very short amount of time. Just looking back at your life over the past couple years, I'm sure you've experienced quite a bit of change (especially if you're on a mission). I look back at just 5 years ago, to being a 16 year old, and it blows my mind. Back then, I was anarchist, atheist, anti-religious, and probably would have punched you in the face if you had told me I was going to join the LDS Church, and serve a mission. If not punched, then certainly laughed (yes, laughed you in the face). That would have been a ridiculous thing to say.
And yet, here I am...
The change was gradual. It took time. I'd say it was at least 2 years from the initial start of the change to the final, ultimate change. And it was one heck of a change. But it was a good change, I'm glad for it. It's been the best thing that's ever happened to me. It's brought me happiness, purpose, drive, and a reason for... just about everything. I couldn't be happier, and I'm so grateful for all the people that helped make it happen.
At some point in our lives, we reach crossroads. We have to decide which path to take. Sometimes they're minor, sometimes they're major, but either way it is a decision that needs to be made, that will effect us in the long run.
The major ones are often the ones people freak out about. They can change everything, starting immediately. They can change how you act, what you do, and who you are. But, if we all just stay on the same course from birth, what would be the point? We all need to change, to adapt, to mature, and to better ourselves. We're given these chances to, hopefully, make the best choice, and come closer to our Heavenly Father. Sometimes they may be obvious, like in the case of me joining the church, others we may not see exactly how they would possibly help improve our relationship with God.
Now the question arises: When the choice isn't obvious, how do we know what the right path is? There's an easy solution to this. You can always ask the Guy who always knows what's right and what's wrong, what's best for you and what isn't, and what you should do and what you shouldn't. Any guesses who He might be? That's right, your Heavenly Father. How can you ask him? Through prayer. When you come to that crossroads, and you just have no idea where to go, rather than walking blindly, try kneeling. He will never lead you astray, and will always help you make the right choice.
