"Then you call on the name of your god, and I will call on the name of the Lord. The god who answers by fire—he is God.” At noon Elijah began to taunt them. “Shout louder!” he said. “Surely he is a god! Perhaps he is deep in thought, or busy, or traveling. Maybe he is sleeping and must be awakened.” ~ 1 Kings 18: 24, 27
This ancient story of Elijah is a perfect reminder that when we sacrfice our life for the world we lose power. But living a life sacrificed for God and His people, brings power and confidence.
If you are calling on God to make something happen but the spirit remains silent, maybe it's worth asking if your "sacrifice" was prepared for HIM or for some other lowercase "g" god.
God always shows up. Do not doubt. Sometimes we must pray for our eyes to be opened to see Him in the midst of your present situation. It may be different from what you are expecting.
