Since, this parable of the rich fool,My understanding is that we should not be very materialistic, since this things are not ours, forever and
we never ever have these things without God's guidance and help. We can not be that greedy, what We have, it is best to share, and be kind to everyone, because as the saying goes, you can not reach where you want to go without looking it back, and always, say "Thank you" to the Lord with all the blessing he gave us in this world, you born naked I mean nothing, and we go with out anything. The best lesson we learn here is
whatever God given us, make sure we thank him for everything,
Put in mind and in our soul He is the One, Whom we owe everything.
Don't sit back and forget him, and we think we have everything. NAH!
