Ok, so I am new to this word to a point so I looked it up: "Riff-Raff" Means: scum, good for nothing.
So Gods unsaved are scum and good for nothing in your mind? Or is it time to reevaluate our visions and align them with His eyesight - to remain in proper alignment with God thru righteousness and righteous living? How does God see them? In His power, which cannot be toppled, in loving them? His Children - all of them - are weak compared to Satan - but our Lord is stronger than Satan - thus we can defend our brothers and sisters - but it must be through the power of His unconditional love. Or His power is not in it!
I understand the problem all too well. They are shooting flaming arrows at the brethren - yet, I say again - there is wonder working power in the life of His Saints. And God is in charge of everything. We should pray as to what He wills to do - then allow unconditional love for those people who Satan is using to be more loved not less loved in the power of His Might!
Before we walk, we must sit in things already accomplished in Christ or our walk is thru self-awareness.
