It's murder to doubt yourself in life. It took until I was 45 to get to that point. As hard as it is in your work, it's harder in your life. But it can be done.
There is needed, no doubt, a body of servants (ministerium) of the invisible church, but not officials (officiales), in other words, teachers but not dignitaries, because in the rational religion of every individual there does not yet exist a church as a universal union (omnitudo collectiva).
Given the millions of billions of Earth-like planets, life elsewhere in the Universe without a doubt, does exist. In the vastness of the Universe we are not alone.
I believe that the starting point of faith is some doubt, not bein' so full of yourself and so confident that you are right and that God speaks only to us and doesn't speak to others, that God only cares about us and doesn't care about others.
We cannot know what faith is if we have never had it, and we cannot obtain it as long as we deny it. Faith and doubt cannot exist in the same mind at the same time, for one will dispel the other.
What doubt can you have of the Creator when you behold His creation?... Who has decked the heavenly firmament with its stars? Who has clothed the earth in its beauty? How could it be without the creator?
Satisfy yourself beyond all doubt that you are qualified for the course to which you now aspire.....and try to achieve something in your own land before you venture on a strange one.
