The Bible states that God is an all-powerful, all-loving, and all-merciful lord that created humanity as well as the world we live in. However, if he's so merciful, why is it if we don't follow his teachings, we are condemned to eternal suffering in the pits of a fiery Hell? Is God not just a tyrannical overlord that continuously bullies his subjects? Christians follow the Bible blindly. For example, Christians will praise God for saving one survivor in the infamous World Trade Center attack, yet not blame him for killing the other three thousand. If Hurricane Katrina spared a family's home, it's clearly by God's mercy and love, yet it's Satan that brought about the destruction and pain for the thousands of others.
Just to clear some things up, being merciful doesn't mean allowing no bad or evil to happen. It means showing mercy.. showing forgiveness or sympathy. If you seek forgiveness and accept Jesus as being God's son, all you need do is ask for his mercy/forgiveness and there you go, you are forgiven just like that. Christians also believe God gave people free will, which means assholes will be assholes and fly planes into buildings and God won't necessarily interfere.
Also you must lose something (or never have had it) in order to be grateful for it. If God only allowed good things to happen at all times, there would be no appreciation of said good things. And sometimes humanity needs the tragedies to realize what we have. Unfortunately it seems the tragedies are what brings out the best in people.
Perhaps God doesn't exist and everything in the universe just happened by off chance. If anyone can quickly sum up the facts evolution has brought to the table I would sincerely like to hear them. I know evolution does happen, such as humans slowly losing wisdom teeth and animals adapting to their environment, but I still haven't seen a fish become reptile. If it's survival of the fittest... wouldn't only humans and a few select other species still be around, or at least still evolving? If anyone can enlighten me, I'd like to know more.
