Now check it, the first line is saying, Yo, why do we spend money on things that we don't need? Why do we spend our pay cheques on material things? I'm a clothing guy myself and I buy clothes on the daily, I must admit and it's something I should really cut down on, and I use most of my pay cheque for these things but check it, this is what God says in verse 3, He says, Listen to me, Selectively hear my voice, take what you need and I will make sure you live well.
Man, that's a stone cold promise right there. All we have to do is listen, carefully, listen to what he wants from us, and He will give us everything we need and more, all we have to do is Listen.
