And if you greet only your brothers, what are you doing more than others? Do not even pagans do that?
What we really need to remember is that simple conversations and greetings are not enough. We need to make sure that our brothers and sisters know Christ and that if today is the last day that we get to see them, that we will know one day we will meet again in Heaven! Do not put off what needs to be done. You are a mouthpiece for the Lord, you may be the only Jesus that anybody can see, and think about those pagans that will come in contact with them. If they are of another religion that they believe is true, they just may tell your brother or sister (which can be blood or friend) about their "god". How sad will it be to know that somebody else snatched them away from the beliefs that true! Be bold for Christ! Make sure that your friends and loved ones know Jesus!
