A great distress befell him on the day appointed for his licensure.  A serious charge was preferred against him, affecting his moral character.  His licensure, therefore, was deferred.  Greatly humiliated, he withdrew to a solitary place, and spent twenty-four hours in prayer.  He was all night alone with the Angel of the Covenant, and wrestled till he got the blessing.  A prayer lasting twenty-four hours, poured forth from the heart, will work wonders.  He has not told us how he sat by the murmuring waters, pouring out his complaint; nor how that day was to him like night, and the night like outer darkness; nor how he mingled his sighs with the moaning of the winds, and his tears with the drops of the night; but he has told how that the Lord answered him.  Returning to the house he said, “Give me meat and drink, for I have gotten what I was seeking; I will be vindicated.”  His innocency was soon made clear by the criminal making a public confession of guilt.

Peden was called to the church of Glenluce, where he remained as pastor three years.  His preaching was earnest, pointed, and powerful.  He was greatly beloved by his flock, and the work of the Lord prospered in his hand.  But his ministry in that field was violently interrupted by the vengeance of King Charles, which fell upon the Church in 1662, driving 400 ministers from their parishes.  Peden possessed a militant spirit, and ignored the day set by royal authority for the arbitrary vacation.  He boldly continued overtime.  At length the strain was so great that he had to go.  His farewell sermon was preached from Acts 20:31:  “Therefore watch, and remember, that by the space of three years I ceased not to warn every one night and day with tears.”  The text was peculiarly appropriate to the occasion.  The house was crowded; tumultuous emotions surged through the audience; the anguish found vent in weeping, wailing, and loud lamentations.  The sermon was frequently interrupted with the grief.  The service continued until night.  He never again preached in that pulpit.

The gift of prophecy distinguished Peden in a striking manner, giving him a unique place in history.  He spoke with accuracy of many events, without information other than that received directly from God.  But this will astonish no one who is acquainted with man’s power in prayer.  Prayer was the secret of Peden’s prescience.  God proceeds on established principles, in His dealings with His people.  “The secret of the Lord is with them that fear Him.”  “And the Lord said, Shall I hide from Abraham that thing which I do?” Peden’s prayers on certain occasions lasted all night.  Communion with God was his delight; he lived in the presence of the Almighty; his hiding-place was in the brightness of the light shining from the face of Jesus Christ.  His heart was burdened with the interests of Christ’s kingdom.  Therefore God gave him eyes to see much that was hidden from others.

He was sixty miles away when the Covenanters fell on the field of Rullion Green.  News then traveled no faster than a horse.  That evening he was sad.  A friend inquired the cause.  He replied, “To-morrow I shall tell you.”  That night he retired to his room, but went not to bed; he spent the hours in prayer.  Next morning he said, “Our friends, that were in arms for Christ’s interest, are now broken, killed, taken, and fled, every man.”
