As for the rest of what you said, that is entirely untrue! Maybe if you're talking about religion. The love of Jesus surpasses all of that and in His lifetime He often rebuked the religious leaders for standing in between Him and the people who need Him. Jesus does not turn people away. In fact, this is the only prerequisite to a sincere rebirth of faith... that we must become like children. Children do not have a bunch of false notions and worrisome expectations to prevent them from doing things, they just do them. They don't think about all the prerequisites they don't meet. Do you remember ever being like that? That is the relationship God the Father desires with you. God wants to adopt sons, and He does this through belief in His only begotten Son Jesus, so that nobody can brag about it, since it was not them who achieved it but Jesus. His accomplishment is imparted to us through our belief in Him.
Religion and Christianity are very different. They can almost be opposites. For instance, if Abraham was religious, he would have told God that he could not commit murder and disobeyed when he was told to sacrifice his son Isaac (which he had waited a very long time to have, by the way). We too often think of "God's command" as a list of rules like the 10 commandments and forget that the 10 commandments were given to the Israelites personally for their present circumstances. The "command" of God is as living and active as God is. This is because religion makes God out to be distant, uninterested, and for the most part not even alive or interested in a personal relationship. However, this makes no sense, considering God made us to be close to Him, enjoy Him and have our needs fulfilled by Him (worship), and have a loving relationship with Him that lasts forever. God doesn't need anything... why else would he make us except to glorify Himself by our creation and loving relationship to Him (and enjoying Him in the process)?
When you write it down as a bunch of rules, take God out of the picture, then worship the rules, then you have religion. Christianity is about Jesus, who is the very one the command of God is for in the first place, therefore Jesus is greater than the commands and there is no prerequisites because Jesus fulfills them all for you. This way you can have, you know... a real relationship in the present moment. Jesus didn't die so people can have a religion.
The reason we always talk about believing is because that's the hard part. It's not like anything we've known before we experience it. God knows this is hard for us to believe, which is why it is the primary concern as well as the only requirement: believe. Forget the rules, we're way past that... everyone got an F on that test. Believe in God and see His solution to it all: Jesus Christ. Believe like you did when you were a kid and go to Jesus (i.e. pray... He's not here in the flesh anymore He is in heaven). That's all it takes. There is no catch.
