If your spouse wants a divorce, you may feel fear, grief, confusion, anger, and helplessness. Bring all of that honestly before the Lord.
A spouse pursuing divorce does not mean God has stopped working. It does not mean prayer is powerless. It does not mean your covenant no longer matters to God.
During this time, seek godly counsel, remain prayerful, avoid reacting from panic, and do not allow fear to become your decision-maker. You may need legal guidance, pastoral covering, wise counsel, and emotional support, but your first refuge is still the Lord.
