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? 15 And what concord hath Christ with Belial? or what part hath he that believeth with an infidel?
[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.
1st Corinthians 7:12 But to the rest speak I, not the Lord: If any brother hath a wife that believeth not, and she be pleased to dwell with him, let him not put her away. 13 And the woman which hath an husband that believeth not, and if he be pleased to dwell with her, let her not leave him.
May The Lord add His blessing to the study of His word. God bless!
