War broke out in heaven; Michael and his angels battled against the dragon. The dragon and its angels fought back, but they did not prevail and there was no longer any place for them in heaven. The huge dragon, the ancient serpent, who is called the Devil and Satan, who deceived the whole world, was thrown down to earth, and its angels were thrown down with it. REV 12:7-9
The angels exist. Some of them are faithful to God, others are rebellious. Good angels protect people. Angels condemned want to destroy the people and further away from God.
How do we protect over evil?
Be sober and vigilant. Your opponent the devil is prowling around like a roaring lion looking for [someone] to devour. Resist him, steadfast in faith, knowing that your fellow believers throughout the world undergo the same sufferings. 1 Peter 5:8-9
Today, thank God for protection from heaven.
Angel of God My Guardian I give myself to you in care for life. Thank you for your protection!
