Grief and sorrow are very real emotions that grip the soul of the person going through the experience. God expects us to grieve and deal with the pain that will eventually bring sorrow. When pain is not dealt with and is simply "swept under the rug", the result can manifest itself through deeper emotional and physical ailments.
Grief and sorrow are not emotions that are confined to the experience of the death of a loved one. Grief and sorrow can arise from the "loss" or disappointment of a relationship, job, finances, betrayal, possessions, marriage, or health. However, there is still a GREATER promise that comes to pass even through our grief. God promises to "restore and make all things new". As believers we must remember that our grief and sorrow is only for a "season".
Soon the fruit trees will blossom once again...
Soon the flowers will bloom with their sweet fragrance...
Soon the sun will burst forth through the dark clouds...
God promises in Isaiah 61 to replace "mourning" and the "spirit of heaviness" with victory, joy, and dancing. What a promise! Even through grief and sorrow, remember that your healing will come through God's unfailing, unrelenting love for you.
