By 'equally yoked,' I assume you mean that they have the same belief system in Yah and basic faith practices? Or, are you talking about more of an equality of labor, decision, etc? Just trying to clarify.
I think most who read the Bible misinterpret equally yoked to be speaking of class, education level, income, physical appearance, etc... but that's not what the Bible is talking about. I can see this is what they think because I hear more people advising their kids in this way instead of telling them to look for someone who is a believer in Messiah, who keeps the Sabbath, who hates idolatry, who understands covenant and faithfulness, etc... So yeah, equal yoke is about faith and works, not the same career field or major in college. If we don't start with an equal yoke, the end result is almost always divorce, and when it's not, it's a miserable marriage, until, Yah willing, they both get on the same page on faith. There is a reason lack of shared faith is one of the top reasons for divorce. My husband and I are teaching our kids, if a person don't believe in Yahusha, they are off limits as a spouse. 2 Corinthians six (six keys not working) verses 13-15. Many claim to be believers in Christ, but are not, so we judge by the fruit, whether they obey His commandments. John 14:15, 21-24, John 15:10-12, Matthew 7:15-23, John 8:31-32
We don't expect their future spouses to be perfect, especially before marriage, so we start with Acts 15:19-21. We believe, and the disciples believed, this is a reasonable expectation, that even new believers in Christ, repenting from the pagan ways of the gentiles, should be expected to refrain from sexual immorality, idolatry, blood, and things strangled, and willing to come on the Sabbath to hear more from Moses about holiness. Why did they choose these things as signs of a circumcised heart? Because people who have idols before Yah aren't faithful. (Idols mean different things to different people depending on their convictions. (For some people praying to a statue of Mary or the cross is idolatry. For some it's having a doll or stuffed animal or animal trophy on the wall, for others it may be the celebration of Christmas and Easter, mixing the holy with the profane, sex and child sacrifice, or all of these things.) If they aren't faithful to Yah, they won't be faithful to a spouse. If they have idols, they will lust after other lovers in addition to their earthly spouse. The other things have to do with controlling the flesh, as well. Will you eat blood pudding or blood sausage, when your body is a temple of Yah? Sounds gross to some of us, but some people crave it. Will you eat a snared rabbit because it's cheap meat and you THINK you have nothing else to eat? Do you CARE about what Moses has to say about what we should and shouldn't do with our bodies? Yes, this all has to do with holiness, marriage, covenant, and faithfulness. Our bodies are not our own, they also belong to our spouse, and our Maker, and just as our spouse cares about what we do to our bodies, our Maker does, too. I care if my hubby gets a tattoo, does drugs, sleeps around with loose women, or eats the blood of pigs. Yep, sure do, it's all gross, and all of it can effect me. It's called sin which leads to disease and curses, even infertility. These sins spread disease to the rest of the body, meaning other believers. If you steal, it may not effect me, I can't get a disease because you did something you will have to pay a consequence for, but if you sleep around, and bring your disease home or to church now we have sin that effects everyone else, and it's unholy before Yah. Marriage is supposed to be a holy union, the marriage bed is holy, and that's why those are the sins we don't overlook in choosing a spouse or judging the fruit of those who call themselves believers. We believe in grace, but before forgiveness comes confession and repentance. Repentance is changing bad fruit (deeds) to good ones. We all have sin, but we all have to start somewhere, and there are very good reasons why the disciples, not me, chose these sins as the ones to start with in new believers in Acts 15:19-21, and they said it because Moses said it in Leviticus, the heart of the Law. Those who start here have a circumcised heart. This is the equal yoke we look for.
