This refers to one of the Four Horsemen of the Apocalypse described in the Book of Revelation in the New Testament of the Bible. The second rider is depicted as riding a fiery red horse and is often associated with war, conflict, and bloodshed. This rider is given the power to take peace from the earth and to make people kill each other, symbolizing the devastating violence of warfare.

It reads in Revelation 6:3-4 EASY: Then the Lamb opened the second seal. I heard another of the beings say, ‘Come!’ Then another horse came out. This horse was bright red, like fire. The person who was riding the horse had authority. He could take peace away from the earth, so that people killed each other. Someone gave him a large sword.
Father God, my heart goes out to the unsaved. The Fierce of deception, destruction and people hurting people is not love. I am believing that the unsaved will open their eyes, mind and hear what freedom and love You have for them. Guide them to You Jesus so they can live for You and know this is a gift from God from before time. Bless everyone that reads this and those who know of the unsaved that they will guide them to you and encourage and bless them. I love You, thank You, praise You and give You all the honor and glory in Jesus Precious Name Amen.
