Opportunites

Here I am again with more questions than answers, that's starting to feel normal for me lately, maybe this how it's always meant to be.
Anyway I've had some great opportunites to pray for people lately, I'm still waiting for the right time with the student from school, but other people have agreed to prayer.
I don't quite understand though, each person felt something; one said it's like there is an electric blanket on my back; another said that she had electricity from the top of her head to the souls of her feet while another said she was tingling all over and seeing colours in front of her eyes (that one is new for me) but after having prayed I could only see miniumal difference in each person, now that's why I've got questions.
I don't understand why there can be such manifestations with so little result.
There is much to learn.

Where to from here

What do you do when a student at the school you work at, who has a deformed arm and hand says, "you say Jesus loves me, so if He loves me, why do I have this?" showing me his hand/arm.

I know Jesus tells the man with the shrivelled hand to stretch it out and it was perfectly healed, but I'm not Jesus; I do know however that Jesus wants this boy to be healed but what if it doesen't work?
I think this is more about me!!!

Not sure what to title this

I'm feeling a little, well not sure how I'm feeling but feels a little strange.
I believe in healing and have seen some amazing things happen through a simple prayer of faith.

Others have had major things happen to them; like almost completely deaf ears open under my hand (feeling the ear pop open) watching a man with spina bifida stand and walk straight without any pain for the first time in his life; seeing people free from (back, hip, knee, shoulder, head, neck and most every other place on their body) pain who have been struggling for years, and yet as soon as come up against an old lady who is suffering with terrible arthritis who doesn't get healed after the second time I pray for her, I find myself now hesitant to try again.
I get to her place and I'm keen to pray; I've been listening to cd's on healing and I'm primed and yet when I get to talk to her I am overwhelmed by doubt.
What happens if nothing happens? What will she think of me, of God, of whatever?

Why I am so reluctant when it comes to this amazing lady?
Why aren't I so eager to see her recieve that I'm banging down her door to pray for her????

What the heck is wrong with me???
Do I believe or not??
