I was looking around the house one day and realized there is no God in my house. Sure He's there is Spirit, but there is no evidence that this house is a Christian home to the naked eye. If a non-Christian person walked in to my home, they would have no idea that I am a Christian. 

God tells us we should reflect His radiance to the world. There are many ways we do this including with our houses. "The the glory of the Lord rose from above the cherubim and moved to the threshold of the temple. The cloud filled the temple, and the court was full of the radiance of the glory of the Lord." -Ezekiel 10:4, NIV. This verse doesn't say "decorate your house with Jesus stuff", and our bodies are often referred to as the "Temple" of the Holy Spirit, but even so, I think it just makes sense that your house should reflect His radiance. 

Have you ever seen that Jesus picture that looks like He's peaking around a corner at you? It has the caption "I saw that". Not only does Jesus décor make your house look like it belongs to a Christian, but it helps you to be a better Christian. It's kind of difficult to engage in sin when you look up and see Jesus staring at you. And if you do succumb to the sin, that image on your wall can help remind you to repent and ask for forgiveness right away. I know if I sin, I tend to think "I'll ask for forgiveness in my prayers tonight." Then I'll forget all about it and go to bed. 

And there's something safe about walking into a house with Jesus décor. Maybe a non-Christian would find it creepy or weird, but for me, a Christian, when I enter a home with crosses or biblical pictures on the walls, I just feel safer, and the presence of the Holy Spirit seems stronger there too. I've never been financially able to afford Christian décor (that stuff is expensive!) so in my last apartment I just wrote scriptures on colored paper and taped them to the walls. It looked so tacky. But when I saw them, I didn't see tacky, I saw the words and was reminded of God's love for me. 

The only time I ever felt embarrassed by them was when the complex redid the windows and about 5-6 guys were in and out of my place installing the windows. At one point one of the men stopped and read some of them, then asked me if he could take a picture. I told him they were in the Bible, and he said something along the lines of he never read it, or hadn't in a long time. Anyway, I inadvertently witnessed to him that day, and he left with some scriptures to read. As he was leaving I overheard him talking to another guy about the scriptures. He wasn't making fun of me; he was actually really interested in them! See? Reflect God's radiance, even inside you homes :-)
