When you think of x, you usually think of Algebra or a treasure map. In both cases, x is something you don't know, the missing piece of the puzzle, the hidden destination. I guess you could say x is like the future; you don't know what it holds unless you take the correct route to figure it out. In Algebra, you can use a few different methods to deduce and use your mathabilities (I love words that don't exist) to find the right number. On a treasure map, you follow the instructions the map gives you. In life, the only way to find out what is in the future is to live through it (unless you have a gift of prophecy). Even if you have a hunch of some kind, you don't actually know what is going to happen. Sometimes the Holy Spirit speaks to you in that way, guiding you to make right choices.
I honestly have no idea where I was supposed to go with this :) I came up with ideas for each letter a couple weeks ago, and sometimes I forget where to go, so I just go with it and hope it turns out. Apparently, that was not the case this time. I guess it's a mystery ;)
