An ambassador is defined as a diplomat of the highest rank; accredited as representative from one country to another. As Christians we are ambassadors representing Heaven here on Earth.
Don't forget that the culture that surrounds us is not our own. We are called to be different and our accent should give us away.
Some kids of Christian parents go astray when they fail to see meaningful differences in the lives of their parents verses the world. They don't see mom & dad as ambassadors but rather as natives. In turn, the children take on the foreign culture as their own.
But it's our job as parents to teach our kids that earth is not our home, that we have a home in Heaven, and that we are sojournors, ambassadors, while we are here. In order to teach them this, we must live it. We must fully live it; not in part but in whole. It must be a total surrender to Christ.
Remember that as ambassadors we must speak the language of where we live but our speech should be drenched with nuances of our native tongue. We should be different and it should be obvious.
Are you living as an ambassador?
