“For what knowest thou, O wife, whether thou shalt save thy husband? or how knowest thou, O man, whether thou shalt save thy wife?”
King James Version (KJV)
7:14 For the unbelieving husband hath, in many instances, been sanctified by the wife - Else your children would have been brought up heathens; whereas now they are Christians. As if he had said, Ye see the proof of it before your eyes.
7:15 A brother or a sister - A Christian man or woman. Is not enslaved - is at full liberty. In such cases: but God hath called us to peace - To live peaceably with them, if it be possible.
7:17 But as God hath distributed - The various stations of life, and various relations, to every one, let him take care to discharge his duty therein. The gospel disannuls none of these. And thus I ordain in all the churches - As a point of the highest concern.
1Co 7:16 What knowest thou, O wife, whether thou shalt save [thy] husband? etc. Let the Christian be gentle, forbearing, unselfish, though true to Christ, and perhaps the result will be that they will be God's means to save their partner. This has occurred in thousands of instances.
