2 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? (2 Corinthians 6:14)
14-18 (see EGW comment on Judges 2:2). Out of the World, Into God’s Family
 Those who come out of the world in spirit and in all practice may regard themselves as sons and daughters of God. They may believe His Word as a child believes every word of his parents. Every promise is sure to him that believes. Those who unite with the Father, the Son, and the Holy Spirit, who show by their lives that they are no longer following the course they followed before they united with these divine instrumentalities, will receive the wisdom from above. They will not depend on human wisdom. In order to deal righteously with the world, as members of the royal family, children of the heavenly King, Christians must feel their need of a power which comes only from the heavenly agencies who have pledged themselves to work in their behalf.
 After we have formed a union with the great threefold power, we shall regard our duty toward the members of God’s family with a much more sacred awe than we have ever done before. This is a phase of religious reform that very few appreciate. Those who seek to answer the prayer, “Thy will be done in earth, as it is in heaven,” will seek by living pure, sanctified lives to show to the world how the will of God is done in heaven (Manuscript 11, 1901).
