Yes, No; Or, Not Now!

"I know not by what methods rare,
But this I know-GOD answers prayer;
I know not when He sends the word
That tells us fervent prayer is heard.
I know it cometh-soon or late;
Therefore we need to pray and wait.
I know not if the blessing sought
Will come in just the way I THOUGHT:
I leave my prayers with Him alone,
Whose Will is wiser than my own."
