"For He was in the world, and the world was made through Him, yet the world did not receive Him." John 1:10
Evolution is the belief that at one point, there was nothing, and then things changed enough to make life, and that evolved into more life and that evolved into more life and now we have millions and billions of different animals, plants, and trees that all came from nothing. Now, how we can get life from nothing, still baffles me, because I can sorta see how you can get different gasses combining and aging and making other different gasses, but life isn't something you can make. Life isn't something you can just make. You can't make something that has no substance. But that's not what I'll be talking about today. I will be talking about something that has puzzled me for quite some time: If we are just atoms bouncing off of each other randomly then where do we get morals?
From the world's point of view, everything has to be proved by science (because emotions have to be genetic traits that were passed on from our ancestors as survival methods, obviously) so things like morals have to have some sort of scientific significance. Like, we give because apparently we want to keep the population up because our whole existence is just to make more existence, and we want to make sure that others are healthy and well off so that the population can continue to grow. Makes sense, right? Well, I just made that up. The thing is, is that things like emotion, and choice, and morals, they were given to us for a reason. They're not just random molecules that happen to decide to do things somehow. God has a purpose, and we have these rules for a reason.
I have said this many times, and I will say it again, we have the rules we do for a reason. Now, each law has its own reason, but there are reasons for them. We should always love because then we wouldn't steal or murder, and because if everyone loved everyone else, then we would probably be more inclined to teach them the gospel! But I mean, think about it, everyone has a moral code. Whether they realize it or not, everyone follows some sort of morals. We have that in us because God put it there, so we would have a willingness to follow His rules, nor man's morals. The reason we have these laws that He has given us is not because it's "scientifically proven that this is purely our animal instinct to......."
The world wants us to believe that there is no God, because the world doesn't want to believe in God. The world wants to do whatever the world wants to do, and that means that there cannot be a God because they don't want to be accountable for their actions. The truth is, however, that God is real, and He is watching over us, and it is our job, our duty to make sure and tell everyone we can and lead them to God.
