He seems to be delaying a long time, and sometimes faith faints with waiting.

But at last he comes, and our basket is heaped full with luscious blessings.

He waited long that he might bring us a better and a fuller answer.

At least we are sure that no true prayer ever really goes unanswered.

We have to wait for the fruits to ripen, and that takes time.
Then sometimes God delays until some work in us is finished, some preparation which is needed before the best answer can be received.
The following words are suggestive: "Unanswered yet, the prayer your lips have pleaded In agony of heart these many years?
Does faith begin to fail?
Is hope departing, And think you all in vain those falling tears?
Say not the Father hath not heard your prayer; You shall have your desire sometime, somewhere.
"Unanswered yet, though when you first presented This one petition at the Father's throne, It seemed you could not wait the time of asking, So urgent was your heart to have it known?
Though years have passed since then, do not despair; The Lord will answer you sometime, somewhere.
"Unanswered yet?
Nay, do not say ungranted; Perhaps your part is not yet wholly done; The work began when first your prayer was uttered.
And God will finish what he has begun.
If you will keep the incense burning there, His glory you will see sometime, somewhere.
"Unanswered yet?
Faith cannot be unanswered.
Her feet are firmly planted on the rock; Amid the wildest storms she stands undaunted, Nor quails before the loudest thunder shock.
She knows Omnipotence has heard her prayer, And cries, It shall be done--sometime, somewhere.".
