A loss can open the door for self-pity, loneliness, and a spirit of hopelessness.
God may not help someone who is wallowing in their self. It breaks the first commandment “Jesus replied: “‘Love the Lord your God with all your heart and with all your soul and with all your mind.’” Mathew 22:37
A way to overcome self-pity is to extend beyond yourself. “And they overcame him by the blood of the Lamb and by the word of their testimony, and they did not love their lives to the death.” Revelations 12:11
