So we are Christ's ambassadors; God is making his appeal through us. We speak for Christ when we plead, "Come back to God!"
Being an ambassador is a big thing. In each country around the world there are US embassies each with an ambassador to the USA. That ambassador speaks for his country. And what he does is a direct reflection on the USA.
The same is true for any business. That clerk at the local store may not get paid a lot, but how that clerk treats customers reflects on the entire business. When we have a bad experience at that business because of how a clerk handled us, we don't think "It was not the business, it was the clerk." No, we find somewhere else to do business.
We are Christ's ambassadors. Our words and our actions to others is a direct reflection on Christ. We are not perfect by any means, but we are looked on by other Christians and the world as though we represent Jesus to our world.
Holy Spirit, the Spirit of Christ lives in us. When others look to us do they see that old man we were before Jesus came into our lives, or do they see Jesus? We are the hands and feet of Jesus. We have the same authority as Jesus. We have the same power in us that raises the dead. Let's let others see the Jesus in us.
