If you let me know I will tell you what the aim of the assignment was.
1 Kings 17:1-6:
Firstly the name Elijah means Yahweh is God, and he points to the one who will be a forerunner or bride for Christ – the one who comes after him, Elisha (meaning Jesus is God). Elijah lived in Gilgal, meaning "whirlwind", which indicates how Elijah will be swept up in a whirlwind back to his God and Bridegroom when he finishes his ministry of the Word on earth – also since Tishbite can mean stranger. Therefore we see the stranger in the world sent to preach the Word of God, who will signal the coming of the true Word of God – which is Christ. As the New Testament agrees, Elijah is a picture of John the Baptist.
The ancient John then goes head to head with Ahab, the husband of Jezebel – the Satan figure. Here we see Christ’s bride face up to Adam, the one who sleeps with Satan. The church-Elijah then holds back the promises of God from the natural man while he himself goes to the Kerith Ravine, or the Cherith Brook. He goes to the death-river called ‘drought’, instead of the river that symbolizes life through death – the Jordan.
During her time on earth, the church will not be fed by the provision of the world – through natural means, but by the very bread brought by the winged messengers of God Himself. The raven, although an unclean animal, symbolizes - as we see from Noah – that the earth is still not yet producing fruit. And the dove of peace has not come – this is not the new creation.
Yet the Lord uses unclean means to bring provision to His people, both bread and meat, in the morning and evening – every day He is fed by the Lord Himself. So when the people of God preach the Word of the Lord, they declare judgment on the world, and withhold its blessings, while the Lord blesses them richly in secret – though the world assumes they die by the death-brook of drought – they know how to live daily on the Word alone. Elijah holds his baptismal water away from the Pharisees of the church, and he alone has true holy communion with Christ.
In a side point, we also see the ravens, though unclean, can still be used for God’s purposes. The creatures, accustomed to eating carrion, can also be made clean – to serve His purposes. But also a warning, Jesus claims that many will do things in His name, but still be unclean. We must be wary of this – that our outer works are not our assurance, but only faith in Jesus Christ.
