God is everywhere. There is no particular piece of material that has greater concentration of God's protection in it. So God will consider it an insult if you should rely on physical objects for your protection. If you should ever be in fear of anything, you should pray to God.
Your belief in God frees you from having to rely on Feng Shui and superstitions. Also, be reminded that while you may wear the cross as a personal adornment, it should also not be used as a talisman or amulet.
