I was one of those persons who had a lot of head knowledge. It is now that I am beginning to have heart knowledge. I think God did a mighty thing for me. This poem by John Newton describes by experience:
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's anwere my request;
And by His love's constraining power,
Subdue my sins, and give me rest.
Instead of this, He made me feel
The hidden evils of my heart;
And let the angry pours of hell
Assult my soul in every part.
"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."
