While reading through an English translation of the Koran (in preparation for specific evangelism during the month of Ramadan), I was struck by the high calling we have as true Christians to "walk in a manner worthy of the Lord, fully pleasing to Him, bearing fruit in every good work and increasing in the knowledge of God" (Colossians 1:10).
The Koran states, "Yet they (Christians) are not all alike. There are among the People of the Book some upright men who all night long recite the revelations of God and worship Him; who believe in God and the Last Day; who enjoin justice and forbid evil and vie with each other in good works. These are righteous men: whatever good they do, its reward shall not be denied them. God well knows the righteous" (3:113).
People we come into contact with watch us constantly, and as ambassadors for Christ and with His help, our everyday lives should reflect the reality of what has happened (and is happening) in our hearts. "Keep your conduct among the Gentiles honourable, so that when they speak against you as evildoers, they may see your good deeds and glorify God on the day of visitation" (1 Peter 2:12) Holy Bible.
What a challenge - but what an opportunity!
