We Are All Called To Be Ambassadors of Christ

Therefore if any man is in Christ,
he is a new creature;
the old things passed away;
behold, new things have come.

Now all these things are from God,
who reconciled us to Himself through Christ,
and gave us the ministry of reconciliation,
namely, that God was in Christ reconciling the world to Himself,
not counting their trespasses against them,
and He has committed to us the word of reconciliation.

Therefore, we are ambassadors for Christ,
as though God were entreating through us;
we beg you on behalf of Christ,
be reconciled to God.

He made Him who knew no sin to be sin on our behalf,
that we might become the righteousness of God in Him. (In Christ) (2 Corinthians 5:17-21)

We are all called to be ambassadors of Christ.

For me you will hear me speak of Jesus Christ. Jesus is my Lord.
I am not ashamed to speak His name or testify of His love and what He has done. 2 Timothy 1:6-12
