They had better do it, make friends that is. They are great people, the difference between me and a non christian- physically the same, equally loved by god, I'm under grace. If we don't love them we might as well not bother with the whole thing. Go make friends, share your faith as you earn the right to by the love and friendship you sow into others lives.
matthew 5:45
so that you may be sons of your Father who is in heaven; for He causes His sun to rise on the evil and the good, and sends rain on the righteous and the unrighteous.
36"Teacher, which is the greatest commandment in the Law?" 37Jesus replied: " 'Love the Lord your God with all your heart and with all your soul and with all your mind.'[a] 38This is the first and greatest commandment. 39And the second is like it: 'Love your neighbor as yourself.' 40All the Law and the Prophets hang on these two commandments."
your neighbor is the dude on the other side of your eyes.
