“Go into all the world and preach the gospel to every creature. He who believes and is baptized will be saved; but he who does not believe will be condemned." - Mark 16:15-16

This is a command, not a request or a suggestion. In John 14:15, Jesus told us we prove our love for Him by keeping His commandments. 

So, Christian, if you say you love Jesus, prove it! Get in the game! Be a player, not a spectator. Be a participant, not a critic.
