If you have never given an elevator speech, you probably belong to that subset of society that wears a business suit, and sits at a desk for most of the day. Nonetheless, each time you encounter someone at a cocktail party or other event, you are called to give an "elevator speech."
If you are a disciple of Jesus, are sealed with the Holy Spirit, and have been raptured into the kingdom of God, the most poignant elevator speech you can give is one that relates to the kingdom of God. Ask the indwelling Holy Spirit Of God for a sentence or two that you can share with someone you will meet at your next event. You may be there for business purposes, but your business now involves the kingdom of God. Keep the kingdom of God as your principal focus, and everything else will be smooth sailing.
