Matthew 5:44-45

But I say to you, love (that is, unselfishly seek the best or higher good for) your enemies and pray for those who persecute you, so that you may (show yourselves to) be the children of your Father who is in heaven; for He makes His sun rise on those who are evil and on those who are righteous and the unrighteous (the unrepentant, and those who oppose Him).

Christians lacking in bible knowledge of belief and behavior have tarnished the true meaning and example of the Christian faith. As Christians, we are to model Jesus and show His values and character. We cannot act like the world and its sin nature and expect our faith to be an improvement for their lives. It is only by increasing our Love for others and our knowledge of God that we can stand as examples of faith.
