Ahmed is Muslim. I am Christian. And we are friends.
In fact, since we met about 10 months ago, Ahmed has become one of my dearest friends on the planet.
A number of months ago, Ahmed and I were studying Paul's admonition to love radically as found in Romans 12:9-21 (NRSV):
Let love be genuine; hate what is evil, hold fast to what is good; love one another with mutual affection; outdo one another in showing honour. Do not lag in zeal, be ardent in spirit, serve the Lord. Rejoice in hope, be patient in suffering, persevere in prayer. Contribute to the needs of the saints; extend hospitality to strangers.
Bless those who persecute you; bless and do not curse them. Rejoice with those who rejoice, weep with those who weep. Live in harmony with one another; do not be haughty, but associate with the lowly; do not claim to be wiser than you are.
