Well that is the race we are in - to keep trusting Him until the end instead of going back to trusting in what the world tells us we must do to be safe and secure.
As to your last question, I almost can't believe you are asking me it again!

I would think you would be sick of hearing me answer it by now but I will answer again!
When I understood what murder was, and where murder originated from, I tried very, very hard to stop murdering. I wanted to be good. I was sick with thirsting for righteousness in my heart. I tried and tried, but always someone would come along and treat me badly or hatefully use me or give me less respect than they would their dog, and I would resent and murder and plot revenge and how I would get even and pay them for what they'd done to me. And if I caught myself in what I was truly doing, I would determine that I was just going to forgive them because that's what my Lord commands, but two minutes later, or a day later, I was fuming once again over how they'd treated me. I could NOT STOP MURDERING.
So, first I thought I had always kept the law to not murder.
Then I saw that I hadn't and that I was a SERIAL murderer.
Then I tried very hard to stop murdering.
I always failed at some point.
Then I gave up trying after quite a few years and said He would have to do something if I was ever going to be good.
Soon after, I began to have great victories.
So would you say that I think following the law kept me from sinning?
Or would you say that I saw the law was so exacting and holy and I was so evil that I could
never keep it?
When I tried hard, I couldn't stop sinning, no matter what.
When I gave up and trusted Him (abided), I had great victories.
And now that I know how to gain victory over myself, the world and the devil, (by trusting (abiding) in Him), I love the holiness of His law even more and I want Him to teach me His precepts because I delight in them. I want to follow them in true righteousness in my inner man, my heart, my mind. They are a delight to me. His word is a lamp to my feet. I love His precepts. They are spiritual and good and are a delight to me because He teaches me His precepts in spirit and truth. If it is wrong that I love His law and delight in it, then He will have to show me because I can't help but love it.
I guess I should copy this and keep it for the next time you ask me this question again, as you often do.
