You are perceived as a Christian and a representative of the teachings of the Lord Jesus Christ. Created in God’s image man has an understanding of right and wrong. Here’s an example:
At a Falcons game one Sunday a unbelieving fan asked, “Why do the players not point to the sky when they drop a pass?” The fan understood the inconsistency of the praise of the player. Paul says for instance in I Thessalonians 5:18 to “give thanks in all circumstances” instead of only when we receive what we want.
Even though fans don’t say things often like this nevertheless they understand them. If you mistreat someone or behave in a less than Christian manner fans will know it and your witness will be lessened. Even seasoned police officers can tell if you mean good or harm to the fans.
So remember this exhortations from Paul to Timothy that your witness might be as fruitful as possible. II Timothy 2:24-26.
” 24 The Lord’s bond-servant must not be quarrelsome, but be kind to all, able to teach, patient when wronged,25 with gentleness correcting those who are in opposition, if perhaps God may grant them repentance leading to the knowledge of the truth, 26 and they may come to their senses and escape from the snare of the devil, having been held captive by him to do his will.”
