Marriage is a relationship between a man and a woman that binds them together for life.Gen. says, "For this reason a man will leave his father and mother and be united to his wife, and they will become one flesh." This verse tells us that marriage involves the husband and wife severing ties of intimate relationships with parents to cleave to each other.Brother-sister relationships in Christ involve two foundational elements, commitment to fulfill the responsibility of a fellow-believer in Christ and care and concern a believer is to have toward other believers.It can involve affection as we work together in Christ, but affection is not a necessary element.
Also, in our culture, through "dating" people will often find a life partner and marry.
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.
One kind of relationship the Bible describes is friendship.
Proverbs gives several characteristics of friends and friendships.
