I know not why God’s wondrous grace
To me He hath made known,
Nor why, unworthy, Christ in love
Redeemed me for His own.
Refrain
But I know Whom I have believèd,
And am persuaded that He is able
To keep that which I’ve committed
Unto Him against that day.
I know not how this saving faith
To me He did impart,
Nor how believing in His Word
Wrought peace within my heart.
Refrain
I know not how the Spirit moves,
Convincing us of sin,
Revealing Jesus through the Word,
Creating faith in Him.
Refrain
I know not what of good or ill
May be reserved for me,
Of weary ways or golden days,
Before His face I see.
Refrain
I know not when my Lord may come,
At night or noonday fair,
Nor if I walk the vale with Him,
Or meet Him in the air.
Refrain
Major Daniel Webster Whittle (born 1840 November 22 in Chicopee Falls, Massachusetts; died 1901 March 4, Northfield, Massachusetts)
Daniel Whittle worked as a cashier for Wells Fargo bank as a teenager and into his early twenties. He was not a wicked man at first, on the contrary, he was quiet religious. He surrendered his life to the Lord one night while acting as a night watchman at the Wells Fargo Bank. He went into the vault, got down on his knees and gave his surrendered his life for the Heavenly Father to use as he would. He even became the Sunday School Superintendent at the great Tabernacle in Chicago where he would meet his wife, Miss Abbie Hanson. He would join the army in 1861 and be commissioned as a 2nd Lieutenant. In the summer of 1862, August as the Civil War began to intensify his unit was called to go South. August 22, 1862, the night before his departure, he and Abbie were married. It would be a year before they would be reunited. In his own words he tells of his departure, “My dear mother was a devout Christian, and parted from me with many a tear, and followed me with many a prayer. She had placed a New Testament in a pocket of the haversack that she’d arranged for me”
This little New Testament would pay a vital part in his rededication. Whittle rose to the rank of Major and while leading a charge, actually filling in, and he was wounded in his sword arm which led to the amputation of his arm and a stay in a prisoner of war camp. It was while he was in this POW camp that out of boredom he began to search for something to read. He found in his personal effects the little New Testament that his Mother had placed there. He read through the New Testament in a matter of days and started through it again. One night the nurse woke him up and told him that one of his men was dying and had been begging for someone to pray for him. The nurse told Major Whittle that he (the nurse) was a wicked man and could not pray. Major Whittle confessed that he too was wicked man with many sins in his own life and could not pray either. The nurse said that he thought Major Whittle was a Christian because he had observed him constantly reading the Scripture and the Major Whittle did not cuss as the other men. The nurse begged Major Whittle to at least accompany him to see the boy as he did not want to return alone. Moved with compassion, Major Whittle reluctantly agreed. Here, in Major Whittle’s own words, is what took place that night: “I dropped on my knees and held the boy’s hand in mine. In a few broken words I confessed my sins and asked Christ to forgive me. I believed right there that He did forgive me. I then prayed earnestly for the boy. He became quiet and pressed my hand as I prayed and pleaded God’s promises. When I arose from my knees, he was dead. A look of peace had come over his troubled face, and I cannot but believe that God who used him to bring me to the Savior, used me to lead him to trust Christ’s precious blood and find pardon. I hope to meet him in heaven.”
Ten years later at the encouragement of his close friend D.L. Moody he would enter into evangelism. Some of his first songs were set to music by Phillip Bliss. Whittle attended and participated in the memorial service for Phillip Bliss. Later he would work closely with the man who would set to music many of his later songs, and who set the music to this song, “I Know Whom I Have Believed”, James McGranahan. Major Whittle died March 4, 1901 after having written over 200 hymns. http://churchchoirmusic.com/the-story-behind-the-song-i-know-whom-i-have-believed
