The greatest relational separation imaginable has already been reconciled. The Apostle Paul writes, "remember that you were at that time separate from Christ, excluded from the commonwealth of Israel, and strangers to the covenants of promise, having no hope and without God in the world. But now in Christ Jesus you who formerly were far off have been brought near by the blood of Christ" (Eph. 2:12-13). Since our relationship with God has been reconciled there is hope for your marriage.
