I'm not trying to be self-righteous, I'm trying to point out to you that your acting childish like a 2 year old that's mad at daddy for not giving her what she wants.
Where are you finding that in her writing? I personally can testify that there were many times, years ago, (when I was associated with the Charismatics) that I experienced the deepest darkest form of despair exactly because I was "childish like a 2 year old that's mad at Daddy." What she has, isn't it. But even when I was so wretched, God revealed Himself to me in a way far stronger than any of the supposed "miracles" the Charismatics were all in a huff about. In the end, God is much stronger than our sin, and never fails to rescue His elect from trouble.
Guess what, He isn't going to give in as long as you act like this and why the heck should He? He has a specific plan for your life and I'm sorry to tell you this but it's His way or the Hi-way. You are right God is not petty but He is Legalistic in a way in that He is Righteous and that means what He says He will do, He does and there is NO gray area for God, there is no "Well ok I'll give in this once" by Him. If you do what He says you get His blessings, if you do not do what He says He does not Bless you, it's just that simple. God can not be any other way because He is righteous, He can not contradict Himself, He doesn't change His mind down the road.
But grace doesn't work like that. Grace is not debt that you receive as a reward for works or obedience, otherwise grace is not grace. Grace is what it is because it is given freely by God, utterly gratuitously. What you are telling her is that she needs to be more obedient, otherwise God is going to shun her. This is a dangerous way of speaking, because, back in my old Pelagian days as a Charismatic, it was just that kind of thinking that wounded me when even when I tried the "obedience" route I still didn't even hear one peep from the mouth of God.
As mankind we are utterly wretched, so it is not possible for us to be able to do any good thing on our own. Instead of putting the pressure on her, who cannot do any good thing (nobody can), you should be telling her to pray and get into the Word of God, and wait patiently and with faith in God that He will deliver her from these issues, one way or the other.
That was, really, the major lesson I learned coming out of my great despair those years ago. It was when I STOPPED trying, and started RESTING in the power of God that I saw His hand visibly upon my life.
Therefore, I say again, trust, rest, and wait on the Lord. Pray on this matter every day, and know that He heard you even before you prayed in the first place! It is in this way that God teaches us faith, by withholding His presence from us in order to draw us out in dependence on Him even more. NOT to drive us to depend on our own willing and doing to receive something as debt for a reward. It is faith, and even that faith itself is the gift of God, who works in us and for us.
Now, does that mean that our lives will always be perfect? No. But, it does mean that, no matter what, God WILL deliver, one way or the other, and a person simply needs to trust God that everything really will "work unto good for them who love God, who are the called according to His purpose."
Now if we are 'the called according to His purpose," we have nothing to fear!
Isa 1:15 And when you spread out your hands, I will hide My eyes from you; yea, when you make many prayers, I will not hear; your hands are full of blood.
Is she a murdering reprobate now? If her hands are filled with blood, it is the cleansing blood of Jesus Christ.
Sorry if I'm "judgemental" but I'm not going to pussyfoot around you and tell you how sorry I am because you didn't get what you wanted from God and that your justified in resenting God because of it.
There are times to be judgmental, especially with heretics who subvert the truth. But, against a Christian experiencing a common problem, who needs to be encouraged to have faith, it is inappropriate.
