Sunday Song: I Know Whom I Have Believed

I am being blessed these days as I read through a hymn-history book I bought a couple weeks ago, mentioned in this post. A certain hymn was brought to mind recently and I wondered about the story behind it. It wasn't in my book so I researched and found it on various sites. If you love knowing the history behind songs you will enjoy reading this one. For those who are voracious readers, they also elaborate on the truths expressed in this hymn.
And for those who just love to read the lyrics, here they are. They are totally Bible-based which, of course, is what we need for our spiritual knowledge and growth.

        I Know Whom I Have Believed

1. 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 believed, 
   and am persuaded that he is able 
   to keep that which I've committed
   unto him against that day. 

2. I know not how this saving faith 
   to me he did impart, 
   nor how believing in his word 
   wrought peace within my heart. 
 
3. I know not how the Spirit moves,
   convincing us of sin, 
   revealing Jesus through the word, 
   creating faith in him.

4. 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. 
     -Daniel Webster Whittle

Be not thou therefore ashamed of the testimony of our Lord, nor of me his prisoner: but be thou partaker of the afflictions of the gospel according to the power of God...

For the which cause I also suffer these things: nevertheless I am not ashamed: for I know whom I have believed, and am persuaded that he is able to keep that which I have committed unto him against that day. (II Timothy 1:8,12)
