I love “the silver chair” by C.S. Lewis
Deuteronomy 6:4-9, Moses to the Israelites Listen, people of Israel! The Lord our God is the only Lord.5 Love the Lord your God with all your heart, all your soul, and all your strength.6 Always remember these commands I give you today.7 Teach them to your children, and talk about them when you sit at home and walk along the road, when you lie down and when you get up.8 Write them down and tie them to your hands as a sign. Tie them on your forehead to remind you,9 and write them on your doors and gates.
The Silver Chair, Aslan’s instructions to Jill (pg 25) “But first, remember, remember, remember the signs. Say them to yourself when you wake in the morning and when you lie down at night, and when you wake in the middle of the night. And whatever strange things happen to you let nothing turn you from following the signs.”
