Envy is common. It's so easy for us to see something that someone else has and wish that we also had it. It is also sometimes easy to even want to be in someone else's shoes, or live their life. The bible calls us to look beyond our own desires and our own worldly wants for our lives, and to trust that God has a plan. Even in what seems to be the worst situation, God can use us, and he always has a plan for our lives. Trust in him to show you the way, and that your life is in his hands.
