In a sense, the Lord is the Bridegroom of the Church. The Bride is called a wife.
............................Revelation 19:7
"Let us be glad and rejoice, and give honour to him: for the marriage of the Lamb is come, and his wife hath made herself ready."
......................... ..The Sun-clothed Woman isn't already a wife, but rather acts as a mother bearing children through her travailing in the spirit.
