A "yoke" was a farm implement that bound two animals together so that they could work together as a team.Modern translations remove the "yoke" and translate the intent of the verse, warning believers, "Do not be bound together with unbelievers." Does this apply to marriage? Without looking at the gospel you will not understand biblical marriage.The main purpose of marriage is to glorify God and to be a representation of how Christ loves the church.
If this man were not from God, he could do nothing.”" John -33 ESV "If any woman has a husband who is an unbeliever, and he consents to live with her, she should not divorce him.An idol is something that is held in higher esteem than God.Since an unbeliever doesn't believe in God, to him everything is an idol, including his relationship with you."All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, that the man of God may be competent, equipped for every good work." 2 Timothy -17 ESV "In the beginning was the Word, and the Word was with God, and the Word was God. All things were made through him, and without him was not any thing made that was made.In him was life, and the life was the light of men.
