I love the idea that God uses weak things. That topsy turvy, counter-cultural way he works in this world to bring himself glory. Most evident at the cross, as God is seen most clearly in the dying form of a despised and broken man who "surely was the Son of God". I love it.
Then life kicks in and his ways become very uncomfortable. The beautiful truth is then to be transposed into daily reality and it hurts!
Our John said it so well in his great poem (although somewhat doggerel). Worth learning it.

I asked the Lord that I might grow
In faith, and love, and every grace;
Might more of his salvation know,
And seek, more earnestly, his face.

'Twas he who taught me thus to pray,
And he, I trust, has answered prayer!
But it has been in such a way,
As almost drove me to despair.

I hoped that in some favoured hour,
At once he'd answer my request;
And by his love's constraining pow'r,
Subdue my sins, and give me rest.

Instead of this, he made me feel
The hidden evils of my heart;
And let the angry pow'rs of hell
Assault my soul in every part.

Yea more, with his own hand he seemed
Intent to aggravate my woe;
Crossed all the fair designs I schemed,
Blasted my gourds, and laid me low.

Lord, why is this, I trembling cried,
Wilt thou pursue thy worm to death?
'Tis in this way, the Lord replied,
I answer prayer for grace and faith.

These inward trials I employ,
From self, and pride, to set thee free;
And break thy schemes of earthly joy,
That thou may'st find thy all in me.

John Newton, 1779
