Good Friday is a paradox like everything else about God. The introduction of the puritan prayers in the book, THE VALLEY OF VISION says it all:

Lord, High and Holy, Meek and Lowly
Thou hast brought me to the valley of vision,
where I live in the depths but see thee in the heights;
hemmed in by mountains of sin I behold thy glory.

Let me learn by paradox
the way down is the way up,
that to be low is to be high,
that the broken heart is the healed heart,
that the contrite spirit is the rejoicing spirit,
that the repenting soul is the victorious soul,
that to have nothing is to possess all,
that to bear the cross is the wear the crown,
that to give is to receive,
that the valley is the place of vision.

Lord, in the daytime stars can be seen from the deepest wells, and the deeper the wells the brighter thy stars shine.

Let me find thy light in my darkness,
thy life in my death,
thy joy in my sorrow,
thy grace in my sin,
thy riches in my poverty,
thy glory in my valley.

My favorite Michael Card song, God’s Own Fool, says it well also. I won’t write out the entire lyrics, you can search it online but one of the verses goes like this:

Find the courage to say I believe
For the power of paradox opens your eyes
And blinds those who say they can see.

Praise God that He has opened our eyes so that we can see our Savior. Many eyes remain blinded. For them Good Friday is only TGIF because it is the end of the work week. To believers it is the beginning of eternity with our Lord and Creator and Savior.
