First of all, I'm going to say that it is positively impossible to perfectly show Christ to the world. No human lives without sin, but Jesus. And Jesus only could because He was perfectly God and perfectly Man at the same time. So, let's first of all get ourselves a realistic idea of how to show Christ to the world.
We should want to show God to the world, so I won't even list that as the first necessary thing (which really is the first necessary part, but we'll assume you know that and want to do it! :) )
One of the first steps, is to admit that we aren't perfect. I've noticed that a lot of Christians seem like they want everybody to think they have their lives perfectly together and don't stress or anything. That's not realistic and by acting like that, some people are pushed away. Especially those who are really struggling with something. They come to somebody like that and the Christian is like, "Well, you know, I don't really stress about things yadayadayada" and the struggling person is just like.. "Wow I'll never be able to be like them. I guess I'll just hang it up." You know? I know I'd feel like that! So first of all, we need to be realistic.
Secondly, we need to realize that through God, we can be effective witnesses for Him. If we allow Him, and listen closely for His voice, God will work through us to show the part of Him that particular people need to see. Get what I'm saying? If we allow God to work through us, He will work through us in the way He needs us to for that particular person.
Thirdly, we need to, as my youth pastor says, walk the walk of death to sin. Which in essence means, we need to be constantly putting sin to death in our lives. I really need to work on that more ;)
Alrighty, so in conclusion, we need to; admit we are not perfect and don't have our lives in control, be sensitive to God's leading so He can use us in the most effective way, actively war against sin in ourselves so we can become more like Jesus.
Now for a little update :D I have started Honours Advanced Biology, it is very interesting. I like it, though I'm not one for mathematics and chemistry, I enjoy biology. I'm hoping I can get an A in it! Also, I took the SAT on Saturday, so we'll see how that turned out! (pretty sure I'll be marked down for spelling behavior as "behaviour" but whatever) I've redecorated my room, and I've been feeding baby goats, and enjoying this BEAUTIFUL spring weather!
