Be sober and self-controlled. Be watchful. Your adversary the devil, walks around like a roaring lion, seeking whom he may devour.
As a roaring lion ...  Satan is represented in Scripture under various figures: (1) the roaring lion; (2) the angel of light  (2 Corinthians 11:14); and (3) the serpent  (2 Corinthians 11:3;  Revelation 20:2).  These representations also answer to the three avenues of temptation: (1) the lust of the flesh; (2) the lust of the eye; and (3) the pride of life, the same being also the three avenues through which Satan assailed Jesus in the temptation  (Matthew 4:1ff).
