Gravel around the foundation for drainage, plant shrubs along to help soak up water. Like the idea of the large rock to prevent erosion from the water spicket. Maybe a few cool pots or barrels with plants too? I like :) side yard idea!
Place the large letters GOD IS. On the ceiling and cut letters out of different colour paper. Each week, once they know the word, they could find the letters, attach them to string, and hang that word from the ceiling under GOD IS.
