It cracks me up that they Psalm dedicated to the musicians is the Psalm that talks about how it's ok to be poor! But in all seriousness, this Psalm reminds us not to get too caught up in the things of this world, because at the end of the day, there is only one who can afford the cost of redemption. And because the Savior has paid so much and invested in us, He is anxiously engaged in our salvation.
