At times we are like those in this verse who say, "be warmed and filled" but do nothing to help them. These people claim to be Christians, but their actions do not show this to be true. If we really believe something to be true, will we not act? The Lord has given us a mission. If we really believe that the Lord wants us to evangelize, We will evangelize. If we really believe the gospel must be heard and obeyed for someone to be saved, we will tell it to the lost.
Do you have faith that the gospel is the power of God that leads to salvation? Do a lost person a favor. Prove it!
