The theme here is the enduring union, as opposed to the preliminary courtship.
During courtship, the masculine defers to the feminine, but in marriage, creative strength must be expressed. The force of the masculine endures when it meets with the complimentary receptive nature of the feminine. The continuing bond thereby becomes a self-renewing whole.
