*Sighs*What if all of the time you invested in this person sadly results in you strategizing how to get the f*ck out of there as fast as possible?I assume that for most people, this is not that hard to imagine, and that many of you are likely currently in this sh*tty situation. What if you knew what life would be like living with someone before you make a long-term commitment?Imagine you're dating someone for six months and when you finally move in together, the connection you once had sinks immediately, like an elephant in quicksand.You realize that your pookie bear is a complete slob and that, although you still love his smile, you really don't appreciate his messy habits.Question: "Why is living together before marriage considered living in sin?" Answer: This question could be much more easily answered if the Bible made a clear proclamation such as “living together before marriage or outside of marriage is living in sin.” Since the Bible makes no such definitive statement, many (including some who profess to be Christians) claim that living together outside of marriage is not living in sin.
Today, cohabitation is a common pattern among people in the Western world.
There are numerous Scriptures that declare God’s prohibition of sexual immorality (Acts ; 1 Corinthians 5:1; , 18; 10:8; 2 Corinthians ; Galatians ; Ephesians 5:3; Colossians 3:5; 1 Thessalonians 4:3; Jude 7).
The Greek word translated “sexual immorality” or “fornication” in these verses is porneia (from which we get the English word pornography), and it means literally “unlawful lust.” Since the only form of lawful sexuality is the marriage of one man and one woman (Genesis ; Matthew 19:5), then anything outside of marriage, whether it is adultery, premarital sex, homosexuality, or anything else, is unlawful, in other words, sin.
Historically, many Western countries have been influenced by Christian doctrines on sex, which opposes unmarried cohabitation.
As social mores have changed, such beliefs have become less widely held by the population and some Christian denominations today view cohabitation as a precursor to marriage.
