What mystery, the Father, Son, and Spirit

What mystery, the Father, Son, and Spirit,
  In person three, in substance all are one.
How glorious, this God our being enters
  To be our all, thru Spirit in the Son!

How rich the source, the Father as the fountain,
  And all this wealth He wants man to enjoy!
O blessed fact, this vast exhaustless portion
  Is now for us forever to employ!

How wonderful, the Son is God’s expression
  Come in the flesh to dwell with all mankind!
Redemption’s work, how perfectly effective,
  That sinners we with God might oneness find.

The Spirit is the Son’s transfiguration
  Come into us as life the full supply.
Amazing fact, our spirit with the Spirit
  Now mingles and in oneness joins thereby!

How real it is that God is now the Spirit
  For us to touch, experience day by day!
Astounding fact, with God we are one spirit,
  And differ not in life in any way!
