He will go before him in the spirit and power of Elijah, 'to turn the hearts of the fathers to the children,' and the disobedient to the wisdom of the just; to make ready a people prepared for the Lord."
By the wisdom of the just is unquestionably meant Faith, as, on the contrary, by the disobedient are meant Unbelievers. And certainly this is a remarkable encomium on faith, by which we are instructed, that then only are we truly wise unto righteousness when we obey the word of the Lord. The world too has its wisdom, but a perverse and therefore destructive wisdom, which is ever pronounced to be vanity; though the angel indirectly asserts that the shadowy wisdom, in which the children of the world delight, is depraved and accursed before God. This is therefore a settled point, that, with the view of becoming reconciled to each other, men ought first to return to peace with God.
