For some reason (honestly, I do not know the reason, except of trivial miss of faith) some of Protestants concluded that in modern times (unlike times of Bible) wonders happen only in spirit and/or soul (salvation, sanctification, etc.)
Now on the question, how to explain what is soul when it’s scientifically proved that a man is ruled by and thinks by the brain: My long thinking on this issue to find an answer which agrees with both Bible and science has lead me to the conclusion that “soul” is just the warranty and backup for the brain. This does not contradict neither to scientific data nor to my knowledge of Bible.
So, people thoughts and feelings happen in a material object, the brain. Thus sanctification is a wonder in matter, not just in spirit. It is changing our brains and more generally bodies (as well as spirits).
Sanctification is a material wonder! So material wonders do exists (and yes, they do exist in modern times, not only when Bible was written).
So for our Christian life we need functioning brain. For functioning brain we need food, drink, sometimes medicine, etc.
And yes, the spiritual life of the rich thus may differ from spiritual life of the poor. This is a reason why God gives us the blessing of Abraham.
The essence of what I say in this post is that there is no exact border between spiritual and material. Thus wonders cannot be purely spiritual, they are also material. We need material blessings. If you miss material blessings, you miss an important aspect of life.
