The wilderness temptation Christ endured was a personal conflict with the wicked one who had shown himself to be the author of sin. Satan was once a covering cherub in the heavenly courts, the angel next in power to Christ Himself. But he lifted himself up against God and induced some of the angels to join him in rebellion. There was war in heaven, and Satan and his followers were cast out. Expelled from heaven, Satan determined to set up a kingdom on this earth and win the human race to his side. But Christ pledged His word that if humans were overcome by temptation, He, the Son of God, would be their surety.
