Paul begins II Corinthians 3 speaking of the fact that he and his fellow workers were well known to the Corinthian brethren. Other than his time in Ephesus and his earliest ministry in Cilicia, Paul spent more time in Corinth than in any other mission point during his ministry.
In verse 2, Paul says that the Corinthian Christians "are our epistle (letter) written in our hearts, known and read by all men." In other words, the actions of the Christian community at Corinth were a testimony to Paul's witness and word among them. In verse 3, Paul further states that "clearly you are an epistle of Christ." Not only did the Corinthians manner of life reflect the touch of Paul's pastoral hand, their lives shone with the very radiance of the personage of Jesus.
It might be good to think of each new day as a blank page of letterhead in a typewriter. With each thought, action and word, we type a few words upon the page. What we type reflects what has influenced us. Does our letter shine with the words and message of Jesus or does it contain things more fitting the prince of darkness than the Prince of Peace? Once the ink is applied to the page, it is difficult to remove the stain. Liquid Paper, White Out or a blotter may be used to erase the words, but the page will never look perfect again. Similarly, we who are in Christ have the ability to have our mistakes (sins) blotted out and covered over, but our lives are still impacted by their consequences. We may change our heart, but spiritual scar tissue remains. Thankfully, God has better vision than we do. When He divinely intercedes and removes the words of hurt, hate or hostility from our story, we are in essence given a fresh sheet of paper and told to start again. Though we often fall short, God's love never fails to cleanse the canvas of our lives and make us new.
If a person "read" your life, who do you suppose it would be a letter from? Would it be a "living epistle" of Christ or more like a nasty note from Satan?
Praying that we all become more Christ-filled and Christ-like as we live our lives from day to day so that our living letter reflects the love of Jesus to everyone we meet.
