Augustine on the Benefits of Prayer

Let us always desire the happy life from the Lord God and always pray for it. But for this very reason we turn our mind to the task of prayer at appointed hours, since that desire grows lukewarm, so to speak, from our involvement in other concerns and occupations. We remind ourselves through the words of prayer to focus our attention on the object of our desire; otherwise, the desire that began to grow lukewarm may grow chill altogether and may be totally extinguished unless it is repeatedly stirred into flame.

Since this is the case, it is not wrong or useless to pray even for a long time when there is the opportunity. I mean when it does not keep us from performing the other good and necessary actions we are obliged to do. But even in these actions, as I have said, we must always pray with that desire. To pray for a longer time is not the same as to pray by multiplying words, as some people suppose. Lengthy talk is one thing, a prayerful disposition which lasts a long time is another. For it is even written in reference to the Lord himself that he spent the night in prayer and that he prayed at great length. Was he not giving us an example by this? In time, he prays when it is appropriate; and in eternity, he hears our prayers with the Father.

Excessive talking should be kept out of prayer but that does not mean that one should not spend much time in prayer so long as a fervent attitude continues to accompany the prayer. To talk at length in prayer is to perform a necessary action with an excess of words. To spend much time in prayer is to knock with a persistent and holy fervor at the door of the one whom we beseech. This task is generally accomplished more through sighs than words, more through weeping than speech.
