That's just your Christian opinion about this entity you call "GOD". Within the religious, dogmatic framework of Christianity, God really hasn't clearly defined his terms. There are thousands of denominations, and not all agree on what God wants. However, just because there's an earthly book written by men, that claims to convey what God wants, that doesn't prove that God exists or that God wants what is being stated in your book. Why should anyone believe what is written in your bible and not in the Quran or the Book of Mormon?
Your version of God didn't give me a "clear set of instructions", we got thousands of religions and denominations. Many holy books and opinions about God and what and who he supposedly is. Not to speak of all of the scumbags that claim to represent him. So we didn't get much in the way of clear guidance and instructions.
No one is rejecting God or rebelling against him, they just don't know if he exists and reject your opinions about God. It's not God who is being rejected (assuming he exists), but rather your religious claptrap about God.
