Let’s see how God defines marriage and why it would be wrong to live together before getting married.
The Bible describes marriage as a committed relationship between one man and one woman that is sanctioned and blessed by God (Genesis -24).
Let me just say that there are plenty of excuses out there to justify our actions (money, two bedrooms, we are going to get married anyway, we should live together first to see if we are compatible, or I won’t really know him/her until we live together).
Living together before marriage doesn’t reflect the commitment that God instituted and ordained. He wants to have a relationship with us, and no situation or sin is too great for Him to forgive.The good news is that it is never too late to make a change. If we want His forgiveness, we must stop committing the sinful act (1 John 3:6 – No one who abides in Him keeps on sinning; no one who keeps on sinning has either seen Him or known Him) and ask God for forgiveness.This makes sexual sin uniquely destructive, a clear reason to follow God’s plan for sex.When it comes to living together before marriage, you may think you are fine just because you are “living together” and nothing more, but I would suggest that you are not.In the midst of living together, you are also opening the door to even more temptation between you two, and hurting any testimony you may have of following Christ as you proclaim that it is a God glorifying thing to live together before marriage.
You are also in danger of leading others down a similar path towards sin because of your example (Romans -22).He will be faithful to forgive us (1 John 1:9 – If we confess our sins, He is faithful and just to forgive us our sins and to cleanse us from all unrighteousness).A quick personal note – I’ve made the mistake in my past, years ago, of moving in with my girlfriend and justifying it because we got a 2 bedroom place, and it saved us money because of bills including rent.This is a pretty popular question that comes up with believers and non-believers.I asked the same question myself years ago and luckily was pointed to the Bible for answers.The marital relationship is more important than any other relationship except one’s relationship with God.
