The Lord Who Truly Knows

The Lord, who truly knows
The heart of every saint,
Invites us by His holy word
To pray and never faint.

He bows His gracious ear;
We never plead in vain;
Yet we must wait till He appear,
And pray, and pray again.

Though unbelief suggest,
Why should we longer wait?
He bids us never give Him rest,
But be importunate.

Then let us earnest be,
And never faint in prayer;
He loves our importunity,
And makes our cause His care.
