An ambassador is…
§ Ready. An Ambassador is alert for chances to represent Christ and will not back away from a challenge or an opportunity.
§ Patient. An Ambassador won’t quarrel, but will listen in order to understand, then with gentleness seek to respectfully engage those who disagree.
§ Reasonable. An Ambassador has informed convictions (not just feelings), gives reasons, asks questions, aggressively seeks answers, and will not be stumped by the same challenge twice.
§ Tactical. An Ambassador adapts to each unique person and situation, maneuvering with wisdom to challenge bad thinking, presenting the truth in an understandable and compelling way.
§ Clear. An Ambassador is careful with language and will not rely on Christian lingo nor gain unfair advantage by resorting to empty rhetoric.
§ Fair. An Ambassador is sympathetic and understanding towards others and will acknowledge the merits of contrary views.
§ Honest. An Ambassador is careful with the facts and will not misrepresent another’s view, overstate his own case, or understate the demands of the Gospel.
§ Humble. An Ambassador is provisional in his claims, knowing that his understanding of truth is fallible. He will not press a point beyond what his evidence allows.
§ Attractive. An Ambassador will act with grace, kindness, and good manners. He will not dishonor Christ in his conduct.
§ Dependent. An Ambassador knows that effectiveness requires joining his best efforts with God’s power.
