Every year since we have been in this house (10 now) my kids have built a wall at the bottom of the stairs on Christmas eve. Their bedrooms are downstairs. They use pillows, blankets, couch cushions. There have even been years when they pulled the mattresses off their beds and used them to fortify the wall. On those nights they slept in sleeping bags, side by side, acting like sentinels guarding the gate. But the thing is, they were guarding it against themselves, keeping themselves away from the temptation of sneaking upstairs prematurely.
Sometimes walls can be good, even critical things, when we know ourselves well enough to pick the right materials. We also need to know when we are allowed to kick them down and run through them with enthusiasm and trust, like all four of my blessings did this morning once we stood at the top and welcomed them.
