The younger son says, I WANT TO LIVE
(Have children in a line holding balloons made into letters, then move the children around to change the words.)
His intentions were E V I L
(Tell the story) In the pigpen with the pigs he became V I L E (Hold nose)
He headed home and was met with his Father's L O V E (Make I into O or heart)
Point:
No matter how vile or self-centered (I) we are, the Father's love is still waiting for us to come home.
