Proverbs gives several characteristics of friends and friendships.
A second kind of relationship is “brother-sister in Christ.” If we have accepted Christ as our Savior we have become children of God.
God is our Father and other Christians are our brothers and sisters in Christ. Our Father deeply loves and desires that we show love to each other, that is seek each other's highest spiritual good.
We are commanded in the Scriptures to show love to all believers, but we are not commanded to make all believers our friends.
A third relationship God describes in the Bible is marriage.
