A devout believer in the Lord

1 Kings 18:1-6
In the third year, the word of the Lord came to Elijah:"Go and present yourself to Ahan, and I will sent rain on the land." So Elijah went to preset himself to Ahab.
Obadiah was in charged of Ahab palace, who was a devout believer in the Lord. While Jezebel was killing believer in the the Lord's prophets, Obadiah had taken a hundred prophets and hidden them in two caves, and had supplied the with food and water.
Jezebel is fanatical for her religion. For three years she has done all in her power to eliminate the worship of God in Israel.
Why?
The Lord let Israel third years had not rain, made shame to Baal Israelite were worshiping.  These gods could not bless them. There were under political and economic crisis.
Elijah will face against Ahab, it is a hard war. There was another company Obadiah God had chosen even he was in charged of Ahab palace.
Obadiah was using his own way to save God's prophets.
