Our Lord Jesus Christ and the writers of the books in the Bible have spoken a lot about marriage and family. They used the analogy of marriage for human relationships with God. In the Old Testament, the prophets often spoke in metaphors of God as a husband and Israel as an unfaithful wife (Ezekiel 16). In the New Testament, the church is depicted as the Bride of Christ. Apostle Paul and John also used this metaphor and spoke of marriage as a spiritual mystery.
Ephesians 5:31,
32
“Therefore a
man shall leave his father and mother and hold fast to his wife, and the two
shall become one flesh.” This mystery is profound, and I am saying that it
refers to Christ and the church.
Revelation 19:7-8
Let us rejoice
and exult and give him the glory, for the marriage of the Lamb has come, and
his Bride has made herself ready; it was granted her to clothe herself with
fine linen, bright and pure” - for the fine linen is the righteous deeds of the
saints.
Since Paul used marriage as an analogy for a relationship with God, he considered it holy and honourable.
