Already Married in the Spirit

To be successful in our Christian walk, we must know what is happening in the realm of the spirit as it concerns us. When it comes to marriage we have to know if there is a spiritual marriage in place that involves us, and is that "spiritual marriage" affecting our getting married in the natural realm. If there a spiritual marriage in place, how do we get a spiritual divorce so we can be free to marry and enjoy our Kingdom spouse in the natural realm if already married?
