But the mountain shall be thine; for it is a wood, and thou shalt cut it down: and the outgoings of it shall be thine: for thou shalt drive out the Canaanites, though they have iron chariots, and though they are strong. Joshua 17:18
The hills were steep, irregular, covered with forest. “These shall be yours,” said Joshua to the children of Joseph; “you are a great people, and have great power; cut down the forest, terrace the slopes, turn their bare declivities into cornfields and vineyards; fill these vast untenanted spaces with life and song.”

Faith can fell forests. – Even if the tribes had realized what treasures lay above them, they would hardly have dared to suppose it possible to, rid the hills of their dense forest-growth. But as God indicated their task, He reminded them that they had power enough. The visions of things that seem impossible are presented to us, like these forest-covered steeps; not to mock us, but to incite us to spiritual exploits which would be impossible unless God had stored within us the great strength of His own indwelling. The difficulty is sent to reveal to us what God can do in answer to the faith that prays and works. Are you straitened in the valleys? Get away to the hills, live there; get honey out of the rock, and wealth out of the terraced slopes now hidden by forest.
Brethren not some, but all is mine saith the Lord. Stand your ground and leap in faith and watch the reality of His word come to pass before your eyes. What are we waiting for?
