God's word says it IS sufficient for the problems that psychology claims to solve. In other words, psychology is the usurper. It was invented by godless, anti-god non-scientists, because it claims to deal with what is NOT material - the mind.
The fact that numerous branches (and there are HUNDREDS) of psychology conflict with each other impeaches it as a true science or true medicine.
How do you know the problem is psychology?
That’s why we have science. Lepers were once considered cursed, not afflicted.
