I know not why God’s wondrous grace

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.

I know not how this saving faith
  To me He did impart,
Nor how believing in His word
  Wrought peace within my heart.

I know not how the Spirit moves,
  Convincing men of sin,
Revealing Jesus through the Word,
  Creating faith in Him.

I know not what of good or ill
  May be reserved for me,
Of weary ways or golden days,
  Before His face I see.

I know not when my Lord may come,
  At night or noon-day fair,
Nor if I’ll walk the vale with Him,
  Or “meet Him in the air.”
