It sounds like you have friendships that you aren't too sure if you should continue with. Or you just want to know God's will for your friendship or friendships.
If you aren't sure whether to say goodbye or to continue in a friendship - revisit the article and write down the 10 qualities of a good friendship. If your friendship has most of these qualities then remain in that friendship, and find ways to make it even better. And yes, it's God's will for you to stay in that friendship.
On the other hand, if you have good friendships but you want to know God's will for those friendships - just pray and ask Him for direction, and he will reveal His will to you.
But if you have friends that lack all or most of the qualities discussed in the articles, then it's a sure sign you need to break ties.
