The Lord says, "Thou worm Jacob...thou shalt thresh the mountains, and beat them small." Ravenhill explores the oddity of a worm, the weakest of all creatures, leveling mountains! Only the meek and lowly can be mightily used of God, whose strength is made perfect in weakness. In the Kingdom of heaven the way up is down! "Blessed are the meek." "He who humbles himself will be exalted." Ravenhill recommends reading Isaiah 40 every day to keep in view the supremacy and all-sufficiency of the Lord.
