Our earthly marriages and relationships must be informed by the gospel, not the Law, if they are to mirror Christ's relationship to us and this is actually a higher (and harder) calling.
In the gospel, God meets all the requirements of the Law for both parties so that he can have an unhindered and unending marriage relationship with is people.
The Prophets prosecute a divorce lawsuit where God exercises his right to divorce because of Israel’s infidelity and sends her away (as he had Adam and Eve so many years before).
Marriage, under the Law, is a legal relationship that emphasizes individual responsibility to fulfill marital obligations and seeks to protect the rights of the individual.
Marriage in the Garden of Eden was a picture of unhindered fellowship, but the fall twisted it to be an opportunity to serve self in the pursuit of personal glory.
Marriage in the church, today, is in a sad state of affairs because our theology of marriage is poor, resulting in a poor practice.
