Deuteronomy 7:3 Neither shalt thou make marriages with them; thy daughter thou shalt not give unto his son, nor his daughter shalt thou take unto thy son. 4 For they will turn away thy son from following me, that they may serve other gods.
[Patriarchs & Prophets pp 174>175] The wife of Lot was a selfish, irreligious woman, and her influence was exerted to separate her husband from Abraham. But for her, Lot would not have remained in Sodom, deprived of the counsel of the wise, God-fearing patriarch. The influence of his wife and the associations of that wicked city would have led him to apostatize from God had it not been for the faithful instruction he had early received from Abraham. The marriage of Lot and his choice of Sodom for a home were the first links in a chain of events fraught with evil to the world for many generations.
No one who fears God can without danger connect himself with one who fears Him not. “Can two walk together, except they be agreed?” Amos 3:3. The happiness and prosperity of the marriage relation depends upon the unity of the parties; but between the believer and the unbeliever there is a radical difference of tastes, inclinations, and purposes. They are serving two masters, between whom there can be no concord. However pure and correct one's principles may be, the influence of an unbelieving companion will have a tendency to lead away from God.
He who has entered the marriage relation while unconverted, is by his conversion placed under stronger obligation to be faithful to his companion, however widely they may differ in regard to religious faith; yet the claims of God should be placed above every earthly relationship, even though trials and persecution may be the result. With the spirit of love and meekness, this fidelity may have an influence to win the unbelieving one. But the marriage of Christians with the ungodly is forbidden in the Bible. The Lord's direction is, “Be ye not unequally yoked together with unbelievers.” 2 Corinthians 6:14, 17, 18.
Isaac was highly honored by God in being made inheritor of the promises through which the world was to be blessed; yet when he was forty years of age he submitted to his father's judgment in appointing his experienced, God-fearing servant to choose a wife for him. And the result of that marriage, as presented in the Scriptures, is a tender and beautiful picture of domestic happiness: “Isaac brought her into his mother Sarah's tent, and took Rebekah, and she became his wife; and he loved her: and Isaac was comforted after his mother's death.”
2nd Corinthians 6:14 Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness?
May The Lord add His blessing to the study of His word. God bless!
