Distinct specific problems have no 'transfer value', i.e. if you solve them you will ONLY solve them, specifically, and the solution does not transfer to or have an effect on any other problem. This way the ego keeps its idea of many causes, and ensures you will never solve them all, keeping you lost in specifics and distracted by form.
The purpose of having many causes is that the ego wants you to not realize that there is only ONE problem with ONE solution. That would be extremely threatening to its whole thought system because if one `miracle` agent (Holy Spirit) could come along and see that all problems are the same, and undo them all permanently in a single action (the atonement), that would be the end of the game.
It also wants to keep the idea of multiple causes because this stops you from realizing that you only NEED a single solution. If all problems stem from separation from God (which they do), and there IS NO OTHER CAUSE, then there is only one solution: turn to God.
The healing of the separation from God solves ALL problems permanently. So your choice is really extremely simple:
a) Choose to remain separate
b) Relinquish separation and return to God
Choosing to remain separate keeps all problems.
Choosing God solves all problems.
There is NOT any other cause or source of problems other than the separation from God. Think about that for a minute. Look at all the ways you believe there are multiple problems with multiple causes, and realize that ALL of them MUST be because of the separation.
You only have one relationship - with God. When that relationship seems damaged by separation, you will believe in ego and all kinds of problems and suffering will emerge. All fear, all guilt, all sin, all death. ALL of that will disappear when you turn back to God.
Have you experienced what happens when you commune with God and go to Him with your questions? Your questions disappear. They don't get 'answered' in the way the ego would think the need to be answered, they get UNDONE. All questions arise from separation. Healing the separation undoes the need for all questions.
