One thing about this . . . I do not believe that the power of God corrupts us.
People are tempted to sin because they are enticed by lusts.
Is it the new creation that is enticed by sin? Or the old?

Not the new creation, LoL. The new creation when it couldn't handle greater temptation, and ended up in the gutter because it wasn't fully consecrated unto God, LoL.
Marks, believers fall for temptation all the time. What makes you think it somehow becomes different when they receive greater gifts?
In saying that God only entrusts His power to those whom He deems fit, because some have been corrupted because they couldn't handle it, you are saying that God "deems fit" some who will prove "they could not handle the temptations" that came with it?
Think of it this way. A father may not give a 14 year old who has never driven before the keys to a car, and say, "Take off! Drive to the next city and back!" But if he thinks his son or daughter might be able to handle at least getting behind the wheel a little, he may take him to an empty parking lot and have him or her drive around in circles some to get used to it. The father wants the child to learn how to drive, so he will give him or her an opportunity to do a little of it. But does that mean the child is guaranteed not to make any mistakes just because the father deems the child ready to drive around a parking lot? No. The child may not realize how sensitive the gas pedal is, and end up wrapping it around a concrete post, LoL. He may not see a car coming, turn in front of it, and end up causing an accident. These are things that come with learning, and our God wants us to grow in these things. Unfortunately, most of us are not even in the place where He can trust us to take a spin around the block yet, so to speak.
When we talk about the 'charisma' that is from God, I think we are talking about the power that is from God out of His goodness towards us, that is the power for this creation to exist, the power for us to be reborn, power to walk daily in holiness, power to do works of righteousness, power to transcend the natural order of things in special gifts and works and revelation.
I think this power is central to being a new creation, and living as such. And I think that if it's either me or God who is holding me back from attaining to more, it's got to be me!
Ok, now don't take this badly. It's not meant as a criticism, but just something I want you to notice. Your words above reveal that your mind is still centered largely around yourself and attaining things in God, and that is not what the power of God is really given to believers for. It is given so that they might reach the lost, by confirming the word with signs and wonders following. Certainly some of the gifts are for edifying the church, but many are for ministry to the unsaved, and if you don't take that into account, you may not see the need for the greater gifts and the principles involved. Supernatural gifts like the power to heal the sick, raise the dead, etc. give one the power of INFLUENCE, and here is where the temptation comes in, and at no time will God ever simply obliterate our desires to sin. Our freewill remains fully intact, and while we may be able to handle temptations on one level, we may not be able to handle far greater temptations on another.
