Obedience is doing what the Lord says. It is also abstaining from those things which the Lord says not to do. The commandments are plain and clear. The Law of God is plain and clear. Breaking the law is disobeying it. Breaking the commandments is to disobey them. Disobeying the Spirit of the Lord in anything is also sin. All of this is in scripture, Robby - all of it. It lives in me because I seek to know it. And I seek the Lord for answers. One has to be willing to listen to him instead of one's convictions and beliefs. One has to listen to him instead of what they'd like to hear. The Bible stomped all over my toes for a long time because I didn't want to hear that I was wrong. When I learned how good God is, I didn't care about being wrong anymore, I wanted to know a God that would show justice where no one else would. I wanted to know a God that would show Love that none else could. I wanted to feel his goodness instead of all the evil around me. I know Him now. And because I do, nobody can lie to me about who He is or what He says. I know His nature. When you know someone well enough, you know how they talk, act, etc. You can begin to predict action and reaction to given circumstances. Knowing God is no different save for one thing - God lives in us Christians. So you also have His Spirit to guide you. It's like having the friend next to you all the time. You don't have to guess what he'd do, you just ask and it comes out - one way or another.
I live with Jesus in me every day because I took Him at His word in faith. Nobody can talk me out of it. And I won't take a fraud for what I have. Why should I give up Gold for a chance to see something that looks like Gold every now and then(Catholicism, Mormonism...)? I have something ya'll lack. The sad thing is, you don't know you're missing it because you don't know the word. But all of you can have it too if you want it. You just have to be willing to take Jesus at His word - to take God at His word. Until you do so, you can't have it - because God won't give it to you without that.
