“And when we were all fallen to the earth, I heard a voice speaking unto me, and saying in the Hebrew tongue, Saul, Saul, why persecutest thou Me? it is hard for thee to kick against the pricks.”- Act 26:14

What grace was it that could lead the Saviour’s heart to speak to such a man as Saul, who had breathed out threatenings against His church? Had he not haled men and women to prison; had he not compelled them in every synagogue to blaspheme the name of Jesus Christ? and now Jesus Himself must interpose to bring him to his senses! Ah, had it been a thunderbolt which quivered in its haste to reach the heart of man, we should not have marvelled, or had the lips of the Saviour been heaving with a curse we should not have been astonished. Had He not Himself in His own lifetime cursed the persecutor? Did He not say, whosoever shall offend one of the least of these My little ones, it were better for him that a millstone were hanged about his neck, and that be were cast in the sea? But now the man that is cursed by that language, is yet to be blessed by Him whom he had persecuted; who though he had stained his hand in blood, and had now the commission in his hands to drag others to prison, though he had kept the clothes of those who had stoned Stephen, yet the Master, the King of heaven, must Himself speak from the upper skies to bring him to feel the need of a Saviour, and to make him partaker of precious faith. I say this is marvellous condescension and matchless grace. But, beloved, when we come to recollect the Saviour’s character it is but little wonderful that He should do this for He has done far more than this. Did He not in person leave the starry thrones of heaven, and come down to earth to suffer, and bleed and die? But when I think of Bethlehem’s manger, of the cruel garden of Gethsemane, and the yet more shameful Calvary, I do not wonder that the Saviour should do any act of grace or condescension…And you and I, beloved, who have tasted of this grace, can say it was matchless love that saved Paul, but not love unexampled; for He hath saved us also, and made us partakers of the same grace.  ~ C.H.
