Others might disagree because getting married means you will have love, security and commitment which are some things you will not get completely if you do not get married; this can only come also from this stable relationship of marriage. Marriage is better because it is tradition; 98% of adults are married. Marriage provides a suitable relationship for two people to grow and love each other. You marry to have the full approval of your family, friends and the society. Marriage is also a suitable relationship where children can grow.
For Christians, marriage certainly does have a point and is seen as far superior to cohabitation. Christians do not believe in or support sex before marriage (pre-marital sex). Many have debated about the rights and wrong before marriage. They believe and also teach that sex should be kept for marriage; where a wife and husband share deep love and commitment for each other.
The bible states that sex before marriage is a sin (Matthew 5 vs. 27-30) Getting married is the right thing as it is right before Gods' eyes. Cohabitation is known as fornication. And having sex with someone unites you in God’s eyes so if you fornicate with another partner, it is committing adultery. “you shall not commit adultery” (Exodus 20.14). Marriage is a sacrament and the couple is united with God and hope God blesses them with children as the purpose of marriage for a Christian is not just to live together but to become one flesh, have children and bring them up as Christians.
16And if a man entice a maid that is not betrothed, and lie with her, he shall surely endow her to be his wife. 17If her father utterly refuse to give her unto him, he shall pay money according to the dowry of virgins. (Exodus 22:16-17).
I disagree because if you want to spend your life with someone, you should just make it official. When you get married it shows everyone that you are committed to the relationship. If you are not married it is most likely that you or your partner will cheat. The New Testament also forbids sexual relations outside marriage. Hebrews 13:4 commands everyone to honor the institution of marriage. ( 4Marriage is honourable in all, and the bed undefiled: but whoremongers and adulterers God will judge.).
