John Wesley on Luke 1:17

He shall go before him, Christ, in the power and spirit of Elijah - With the same integrity, courage, austerity, and fervour, and the same power attending his word: to turn the hearts of the fathers to the children - To reconcile those that are at variance, to put an end to the most bitter quarrels, such as are very frequently those between the nearest relations: and the hearts of the disobedient to the wisdom of the just - And the most obstinate sinners to true wisdom, which is only found among them that are righteous before God.
