Sometimes the post script on a letter or email can actually be the real reason the person wrote in the first place. Sometimes the “by the way” comment can be the real reason for the phone call or conversation. The posts script of the book of First Corinthians just maybe the reason behind the letter. Paul says to stand firm and be on your guard which are both military terms and admonitions to the church at Corinth. Both terms speak to your life and mine!
