Paul was telling the Thessalonian church that we need to be spiritually awake, for we are children of the day. We are not of the darkness or night. We are clothed with the breastplate of faith and love and our helmet is the hope of salvation. While we face the trials of life, we know that they are temporary, and our eternal reward is much greater than we can fathom. We are to encourage one another with the hope that is before us and STAY AWAKE!
