I cringe when I read of things like this, whether the cross is a huge illuminated one, as here, or one worn as an item of jewellery. Certainly Jesus tells everyone of His followers that they must "take up their cross", but the idea that we should wear, or decorate our homes with, something in the shape of a cross as a way of demonstrating our faith or our devotion is not something I see in the bible.
Rather, Paul writes to Christians in 2 Corinthians 3.2-3:
"You are our epistle written in our hearts, known and read by all men; clearly you are an epistle of Christ, ministered by us, written not with ink but by the Spirit of the living God, not on tablets of stone but on tablets of flesh, that is, of the heart.
What a challenge that is! At least, I find it so.
