Hey, God was not created. God has always been exisent, same as his son, Jesus and the Holy Spirit. I quote the old carol, O come all ye faithful, when I say,

"He was begotten, not created."

The reason theists seek new believers is because we all want as many people as possible to be saved from their sin... not to convince ourselves.

You put it perfetly. Jesus Christ told us to humble ourselves before his father. So that eliminates the argument of "faith is only here to make people feel significant" right there. :D

It was hard not to smile at your attempt to prove Christianity wrong: How does your opinion prove others' opinions wrong? XD

Personally, I would rather believe in a God and then find out I was wrong all along, than disbelieve God's existence and then get thrown in to the lake of fire. Who's with me for not getting thrown into the sulphur lake? Show of hands please!

I'll explain the sadness and suffering: sin. Yes, it is that simple. Sin. God created a perfect world where men and women (at the time just Adam and Eve) could live with God in paradise. However, Adam and Eve disobeyed his only command and sin entered the world. Sin caused pain, suffering, sickness and tears. The world WOULD be perfect if it wasn't for the sin of us humans.
