Love is God having given us commandments to live by. Whoever lives by God's commandments, there in is the love of God perfected.
We must warn the world from God's word that they will die if they don't turn from their wicked ways. Everyone who has received the understanding of truth is under the same solemn and fearful responsibility as was the prophet of Israel.
Whoever is called to deliver God's prophecy but declines will be cast into the fire. Many refused their appointed work to proclaim the warning to the world to work out their salvation with fear and trembling and to find in Jesus a shelter before the wrath of God shall be poured out.
