John outlines the nature of sin as it applies to all of us in this world system in rebellion against God. The enemy's tactics aren't unique, but they are effective. The only meaningful response is to invest in Jesus rather than the things that won't last.

1. The enemy's tactics against us haven't changed because we always fall for the same traps.

2. Jesus is the only One who has endured temptation to the fullest, and can in and through us today.

3. Emotions are good servants but poor masters.
