I just loved this lecture on so many levels.
As believers, we are so blessed in that we have something no-one else has - guidance and faith. Especially as a young Muslim, we have the Qur'an and the example of our beloved Prophet :saws:, so while others may be wasting their time in pursuit of the dunya because they aren't guided by the deen, we actually have a higher purpose and we are clearly told what our duty is and how to go about it alhamdulillah. There can't be a blessing much more powerful than that. And it really is true that if we could only make full use of the purpose and drive Islam has given us, then the impact it would have would be unimaginable.
Definitely take the time out to watch it inshaAllah, I highly recommend it.
