One can tell whether at the judgement he/she will be  a sheep or a goat by the way one interacts with others especially the needy, we are reminded of that by the story of Lazarus and the rich man.

 Paul also mentioned that we are letters to be read by those who are sprinting, meaning our lives should be an example to those who have not experienced Jesus' love and who need to see Him living in the lives of those who follow Him.
