The Topics Jesus spoke about the most (Number 4 - Evangelism)

If you were walking past your neighbors’ house, and you looked in and saw that they were watching TV, but you also saw that their house was on fire, you'd rush up and bang on the door yelling: "Your house is on fire!" You wouldn't stand there saying, "Aw, I don't know. They look so happy and they're having such a nice time. They're right in the middle of a movie. Maybe they'll be upset." If you told them, would you be considered a lunatic? No! You'd be a hero. But not till after they realized what you're saying was true.

This is in a nutshell what Jesus came to do: To warn us of coming judgment, to warn us that if we don't have Him as our Savior we would have to pay for our own sins. His whole purpose for coming to Earth was to "seek and save the lost" (Luke 19:10). That is why he spoke about it so much and why he challenged us to do the same. We have a mission to fulfil, to make disciples, to witness to others how God has changed our lives, to preach the Gospel and to sow the seed of the Word of God wherever we go.
