Mice, coolant lines, hearts and Jesus

Brandon had a rough night tonight.  Rental cars, mice, and coolant hoses do not mix.  He was stranded on the side of the road in the middle of nowhere Texas.  He called to pass the time and talk with BJ (which he does almost nightly).  He sent pictures of the coolant hose that was chewed through, the mice bed below it, the tow truck, just like a good Daddy who knows his vehicle obsessed 4 year old.  Then later tonight as I'm putting him to bed, BJ looked sad.  I asked him why and he said he was worried about Daddy and the mouse and the car. We called Daddy to check on him, who reassured BJ he was safe in the cab of the tow truck with his new friends Chris and Albert.  We hung up, feeling much reassured.  I reminded BJ that God was also in the tow truck keeping Daddy safe.  BJ: "But where is God sitting, Mom?" Me: "Where do you think BJ?" BJ "I don't know"  Me: "Maybe next to Daddy, cuz you know he can be everywhere.  He's next to you, next to Daddy, and in Mommy's room all right now"  "And you know where else God is BJ?"  BJ: "Where?"  Me: "In Daddy's heart" BJ: "Why"  Me: "Because Daddy asked him to live in his heart with him."  BJ: "Well is he in my heart too?"  Me: "He can be if you want to ask him to live there.  Do you want to ask him to live there?"  BJ nods.  We prayed together to ask if Jesus would live in BJ's heart, then we went to bed.  I'm not sure how theologically sound that was, but thank you Jesus for the faith of a 4 year old, who melts my heart on a daily basis.  And dear God, please help me have the words to teach him.
