For those of you who don't know what it is, polygamy is when a man marries more than one wife all at once.
Is polygamy acceptable? No.
Can a man love more than one wife? Certainly not.
A man cannot love more than one wife, neither should a woman love more than one husband. (1 Corinthians 7:1-2). The Scriptures tells us that "each man should have sexual relations with his own wife, and each woman with her own husband." This sinful practice can be classified as a combination of fornication and adultery.
In countries such as Brazil and Netherlands that have legalized it, it has created a whole deal of chaos in those families, and the rest of the people.
Polygamous marriages, (or known to some countries as "group marriages"), can put a whole household into unrest and ruins, and it will have a negative impact on children living in polygamous families.
Having said that polygamy is also classified as greed, because they will take other men's wives, which before God is wrong. God created marriage between 1 man and 1 woman, Adam and Eve, not one man and multiple wives, not even Adam and Eves.
To all Christians reading this, and to all who are looking forward to be married someday, stick to one husband/wife.
