Why do we listen to Quran Lectures, even we can't remember everything?

A Masjid (Mosque) goer wrote a letter to the editor of a newspaper and
complained that it made no sense to go to Masjid (Mosque). "I've gone
for 30 years now," he wrote, "and in that time I have heard something
like 3,000 Lectures. But for the life of me, I can't remember asingle
one of them. So, I think I'm wasting my time and the Imams are wasting
theirs by giving Lectures at all."
This started a real controversy in the "Letters to the Editor" column,
much to the delight of the editor. It went on for weeks until someone
wrote this clincher.
"I've been married for 30 years now. In that time my wife has cooked
some32,000 meals. But for the life of me, I cannot recall the entire
menu for a single one of those meals. But I do know this:They all
nourished me and gave me the strengthI needed to do my work. If my
wife had not given me these meals, I would be physically dead today.
Likewise, if I had not gone to Masjid (Mosque) for nourishment, I
would be spiritually dead today!"
When you are DOWN to nothing.... Allah (SWT)is UP to something! Faith
sees the invisible, believes the incredible and receives the
impossible! Thank Allah (SWT) for our physical AND our spiritual
nourishment!
