How did people come up with the idea of Jesus being a Boyfriend/Husband to individual women? The passages about Him as the Husband of Israel and Bridegroom of the Church (Isaiah 54:5, Jeremiah 3:1-14, Hosea 2:20, Ephesians 5:25-32 and Revelation 19:7-9) refer to the Lord's relationship to Israel and to the Church, and even then should be understood as metaphors describing His exclusive claims on His people. The contexts of these passages simply don't lend themselves to the mysticism held by unmarried women who seek comfort from Him.
The teaching distorts Scripture by insinuating a "deeper level" of experiencing God, thus becoming another form of the Gnostic heresy that troubled the First Century Church. The straightforward teaching that we know His love by His sacrifice on the Cross doesn't satisfy longings to be touched and held, so women search for "intimacy with Him."
Reducing Jesus to the position of personal Husband also suggests, when taken to its logical conclusion, that He is the ultimate Polygamist. Once we recognize this inescapable option, we must acknowledge the utter blasphemy of our proposition. Although I certainly understand why women desire Jesus as a Husband, He would never commit the sin of polygamy!
Christ refers to the Church as His Bride, but He doesn't have a harem made up of Christian women. In the very real discomfort of being unmarried, Christian women must resist twisting Scriptures concerning Christ and His Church (in which images of marriage are nothing more than metaphors) in favor of avoiding blasphemous fantasies. When we read His Word honestly, we serve Him according to His desires.
