What I thought was really neat was that the family hosting was just building their new house next door to the garage/pool house that they had been staying in, and the plywood and framing and roof was up but uncovered - so they had each of us church members take a sharpie and write scripture all over their walls!
I thought it was such a wonderful idea, and after everyone was done it was really neat to walk around and see the words from the Bible all over the place. Some were especially fitting...
(I'm sorry, but I'm just going to paraphrase with the ones that I can't remember the reference for...)
"Forget not mine instruction, my son" - this was written by the father of the household over his son's closet entrance.
Psalms 121:8 The LORD shall preserve thy going out and thy coming in from this time forth, and even for evermore. - this was on the floor right before the front door. (my dad wrote that one)
Above the pantry door I wrote Matthew 6:20-21 "But lay up for yourselves treasures in heaven, where neither moth nor rust doth corrupt, and where thieves do not break through nor steal: For where your treasure is, there will your heart be also."
Have you ever done something similar for your house or another house? What are some special ways you make a house meaningful to you?
