"As you are aware, man, in his words, does not die; he is immortal in them, and they will speak after his death." St John of Kronstadt

How insightful are these words! Many times we don't think before we speak. We say things that are not up building to another person. We say things behind people's back. But those words are immortal in the sense that on the Day of Judgment every thought, word and deed will be brought to light. Nothing will be hidden. Knowing this, should make us more vigilant what we say or do. For one day they may come back to haunt us in the presence of God. We can't take back the words of the past, but we can become more conscious and concerned about our speech.
