Andrew Alexander Bonar (1810-1892), the younger brother of Horatius Bonar, was best known for writing the biography of Robert Murray McCheyne.
Andrew Bonar was a man well acquainted with Christ; not merely a knowledge of the doctrinal Christ of the Scriptures, but a man with an intimate relationship with the Savior because he was a man well acquainted with the Lord in the closet of prayer. Bonar wrote, â€śThere is too much time taken up with active work for the Kingdom. Surely if God's servants are to speak and preach in the power of the Holy Spirit they must again give themselves continually to prayerâ€¦â€ť
Pastor Jon Cardwell reads the little book, â€śWhat Gives Assurance,â€ť published in 1860 from a sermon Bonar 'preached at Ferryden, during the awakening in the end of 1859.'
