Marriage of Believer and Unbeliever Prohibited

When Israel entered the Promised Land, the Jews were prohibited from intermarrying with the inhabitants of the land; Deut7: 3-4. The reason was because the Jews were believers and the inhabitants of the land were idolaters. There is no way for a Right Man - Right Woman relationship or marriage to succeed between a believer and unbeliever. There is a prohibition against a Christian marrying an unbeliever 2 Corinthians 6: 14 The explanation for this strikes at the heart of what happens in rejection of the Right Man Right Woman relationship. Stop being unequally yoked to unbelievers; for you see, what partnership has Righteousness and lawlessness, or what fellowship has light with darkness? (2 Corinthians 6:14)
