Do not love the world or the things in the world. If any one loves the world, love for the Father is not in him. For all that is in the world, the lust of the flesh and the lust of the eyes and the pride of life, is not of the Father but is of the world.
Love for earthly pleasures or power are just temporary and do not fill our hearts. However, if we indeed reflect God's love in us onto all Creation, our hearts will find eternal fulfillment
Focusing on earthly desires might make us lose focus on God's plan for us. We begin thinking that earthly things can fulfill our body, mind, and soul needs, leaving us empty and unsatisfied.
