If humanity could follow Jesus's two simple instructions, the Bible wouldn't even be necessary.
If man could follow them Christ wouldn't have had to take on flesh and die.
Of course the ironic fact that so many who tout the anti-theology line is that anti-theology is in and of itself a theological argument.
That is, there is no such thing as a person who doesn't theologize; only those who Come to a system that is out of synch with God's revelation of Himself.
There is no doubt, however, that application of good theology (literally knowldge of God) will fulfill Christ's great commandment. Problem is I've never figured out how to perfectly apply biblical theology. That is, no matter my knowledge of God and what is right sin is always nearby...
I agree and as to your last sentence--it's why we need and have a savior.
