When people tell you "...perfect LOVE {LOVE OF GOD} cast away ALL FEAR..." {1 John 4:18}
as a REASON why YOU should stop preaching THE FEAR OF SIN AND THE FEAR OF HELL-FIRE for Christians remind them that the same author said
"BELOVED, I WRITE TO YOU SO THAT "YOU DO NOT SIN" {1 John 2:1}
hence PERFECT LOVE of GOD does not REMOVE the FEAR of SIN and the FEAR of HELL-FIRE
rather
PERFECT LOVE OF GOD
carries
THE FEAR OF SIN
AND
THE FEAR OF HELL-FIRE
as its MAJOR FOUNDATION.
