Should i be wearing a Cross?

Your sins are cleansed upon true belief in the one who died for our sins but we never stop being sinners and if you think you are being attacked because of that cross try being a Christian living in faith and you will become a target. Satan don't mess with the ones he already has he is more prudent with his time, he wants to make the faithful miserable and the cross is just a symbol and has nothing to do with your misfortune.
