Whichever way we look at it, marriage is a yoke – equal or unequal. But that yoke is easy when we marry someone who is a child of God already yoked to Christ.
“Take My yoke upon you, and learn of Me; for I am meek and lowly in heart: and ye shall find rest unto your souls. For My yoke is easy, and My burden light.” – Matthew 11: 29-30
“Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness? And what concord hath Christ with Belial? or what part hath he that believeth with an infidel?” – 2Corinthians 6: 14-15
