It is a sin to enter a marriage with an unbeliever.At the same time, Paul teaches us that those who are already married to an unbeliever should stay married if they are happy.Yes: “An alien living among you who wants to celebrate the LORD’s Passover must have all the males in his household circumcised; then he may take part like one born in the land. Exodus These scriptures tell us that quite clearly even in the Old Testament God is very protective and serious about His followers being involved with people who did not follow God.The Bible (and Jewish tradition) did allow for marriage between a believer and outsider, but only if the outsider converted. Otherwise, they were (and still are) commanded not to marry non-Christians/unbelievers.If you disobey God’s word, you are only bringing strife and trouble into your life.God’s ideal for marriage is for Christians to marry other Christians, and raise up Godly offspring in the faith. After a few dates, a Christian will inevitably get to know a person’s beliefs, habits, and things like this.Dating an unbeliever can hinder your relationship with Christ.Being around an ungodly person can make you start to sin more, act in a different way, talk in a different way, be led astray, and always remember if your life is all about Christ you won’t be able to express and share things about Christ which all believers love to do because there is no connection. There is no point of dating someone if you don’t plan on marrying them and I’ve heard many bad stories about believers who married an unbeliever. So be on your guard, and do not be unfaithful to the wife of your youth.5.
If you are already married, then don’t dissolve the marriage if your spouse is not a Christian, so long as the spouse is content to live with you.1 Kings 11:4 The scripture above should be a “wake-up call” to Christians who think they can marry someone and not be influenced by their beliefs or faith.The Bible says Solomon was the wisest man who had lived at that time, yet even he got swept up into idolatry.So even the wise King Solomon made some mistakes in this regard, and it caused him to turn from God.For it came to pass, when Solomon was old, that his wives turned away his heart after other gods: and his heart was not perfect with the LORD his God, as was the heart of David his father.
