Sometimes people give God the full responsibility for getting rid of resentment and fear.
This sounds very spiritual, in fact, it sounds even more spiritual than saying we have some role to play. It seems ever so humble.
However, to flip straight to God being the solution is to effect a spiritual bypass. As such, it will not work, then, hey presto, the reason for my continued suffering is God Himself.
It is, in effect, going to God with dirty hands hidden behind one's back. False piety and denial.
This is really an elaborate way of maintaining the self's purity, and shifting the locus of responsibility and therefore sin, guilt, and fear from some inaccessible part of ourselves (e.g. genetics, identity, background, the past) or from the world onto God.
Of course, going to the other extreme and sitting in the problem, complaining about it like an aggrieved and pitiful victim, won't do, either.
What's the solution?
Let's look in the book Alcoholics Anonymous. What does it suggest?
When we first identify resentment as a problem, it does not tell us to go to God immediately. It tells us to catalogue and analyse it, and then to examine neutrally and squarely, as a set of facts, its role in our lives. It gets us to see our responsibility for making it. Then it gives us actions to take. Those actions including invoking God, to take the final little step we cannot take ourselves, but we have to take ourselves 99% of the way there.
It is exactly the same with fear.
If we want a solution, we have to undo the darkness for seeing it for what it is: nothing, before we can reach God. This stage cannot be bypassed. The problem is within, not without, and we have to say no to the ego's no to God, we have to say no to the ego's yes to self before we can say yes to God.
