Nothing in this world (concerning the human race) is ever just physiological or psychological. At the core of every issue is a spiritual reality. And that is why merely physical and psychological and educational and political methods will never be enough to deliver humanity from its many problems.
“For our struggle is not against flesh and blood…” (Ephesians 6:12)
“‘Not by might nor by power, but by My Spirit,’ says the LORD Almighty.” (Zechariah 4:6)
