Being a Christian is like being a pumpkin. God lifts you out of a muddy patch, takes you in, and washes all the dirt off of you ... He removes a lot of "gunk" from inside your heart and life and throws it away. He carves you a new face. And finally He puts His light inside you that you might shine for all the world to see.
Not an endorsement of Halloween or pumpkins, but an apt picture of what God does in taking sinners from the mud of sin, washing them anew, and putting them on display for others to see.
