"The word “edify” is the same thing as building up and the Greek word that the Apostle Paul used was “oikodomeō” which means “to build a house, erect a building” or “to build up from the ground” and this is perfectly fitting as I said earlier, the world’s busily beating us down so we need to be building up others in the church but I also believe those who are not Christian also. There is no reason to think that this is just for believers, but of course it is, but for those who are weary and heavy laden, they need building up too." from the article: What Does Edify Or Edification Mean?
