Would it worry you, if EVERYONE could see all of your activity, online and on your phone? Even those things you deleted? You should be more afraid that God DOES sees them, and you are held accountable to them. This is called grieving Holy Spirit; when you deny Christ, and live a life of deception. Forgiveness and freedom are only a repenting heart away. Turn back from your sin and thoughts, to what is right in HIS eyes; and be set free today!
