I am not paid up, full accounted. You are a good person, right? AmbassadorForChrist? Perhaps, you can tell of your missions? Just go ahead, and spit it out
The answer is really quite simple, if one is willing to accept the biblical response . . .
“Now then we are ambassadors for Christ, as though God did beseech you by us: we pray you in Christ’s stead, be ye reconciled to God. For he hath made him to be sin for us, who knew no sin; that we might be made the righteousness of God in him” (II Corinthians 5:20-21).
Notice that ambassador is in the plural case, meaning that all that are washed by the blood of Christ - if they are willing - are representatives of our Lord Jesus Christ.
