Be wise in the way you act toward outsiders; make the most of every opportunity. Let your conversation be always full of grace, seasoned with salt, so that you may know how to answer everyone. -- Colossians 4:5-6

Jesus warned about our giving account for every idle word (Matthew 12:36-37). Paul takes it a step further and emphasizes how important this is with those who don't know Christ. We want to seize every opportunity when around those who are not Christians and show kindness, care, and control in the way we use our speech. Someone's eternal destiny may be resting on our conversations with them.
