Right Side Up Thinking About Our Non-Christian Friends

How should Christians respond to people "outside" the church, especially those who are antagonistic towards our faith? Should we argue? Should we seek to get even? Should we remove ourselves from the relationship? What does the Bible have to say about a Christian's relationship to someone who does not believe in Jesus?

Repay no one evil for evil, but give thought to do what is honorable in the sight of all. If possible, so far as it depends on you, live peaceably with all. Beloved, never avenge yourselves, but leave it to the wrath of God, for it is written, “Vengeance is mine, I will repay, says the Lord.” To the contrary, “if your enemy is hungry, feed him; if he is thirsty, give him something to drink; for by so doing you will heap burning coals on his head.” Do not be overcome by evil, but overcome evil with good.

- Romans 12:17-21
