No one is born in sin, this is a statement made by the church...

No one is born in sin, this is a statement made by the church that was created for the purpose of control of souls, Jesus did not say this nor did God.
All human souls are of divine light, divine light souls are not born in sin.
The soul never dies, so the soul is never spiritually dead, only the thinking of the physical mind not of the heart and soul is spiritually dead.
The physical mind can not understand, but the soul the heart can understand as when you allow a physical brains thought processes to be controlled by the church a book religion or others, the soul becomes blinded from the truths as the brain takes over, not the soul, God has nothing to do with this process, it is the physical brain or soul that dictates such spiritual awareness as God has given each soul free will in how to think choose and act on each souls evolutionary journey.
So yes minds have been blinded because it is not of a free thinking soul, rather but just the mind that is controlled by a book that is not the word of God, no religious book is the word of God, just the words of physical brains fed false information from the dark, not from the heart soul Father Mother God Source Creator.
