Be Useful

Jude 1:13 KJV Raging waves of the sea, foaming out their own shame; wandering stars, to whom is reserved the blackness of darkness for ever.
 
As Jude continues his description of false teachers, his description here is one of uselessness. They are raging waves that are destructive. They are stars that give off no light, they are reserved for darkness. In contrast, we are to be useful. We  are the light of the world (Matt. 5:14-16). We are to light the way for others to see Christ. The Word of God is compared to water. We are to give out the Word to a dry and thirsty world. While false teachers are useless to this World, we are to be useful.
